I remain amazed that many people insist that T'Kuvma and company are irreconcilably different from the TNG era portrayals. These are big, carnivorous-looking aliens with prominent forehead ridges and significant individual variation in appearance. They're different in some small details, like the extra nostrils, but outside of the most extreme visually literalist stance, is it really that hard to square these guys against Chang, Martok, and Worf? Replace the shine and detail with a classic rubber mask, silicon makeup, and matte brown body paint in exactly the same head and body shape, stick them at a side table in Quarks circa S6 of DS9, and I challenge you to notice anything amiss.

What this rework did do was make them feel so much more alien, and so much more dangerous. They outright eat people, which was occasionally hinted at but is noted far more literally in Discovery, and very, very easy to believe looking at these guys. I wish they hadn't backpedalled so hard with a return to the 1980s makeup in SNW 2x01, because I would have loved to see these monsters chumming it up with Spock: that scene would immediately have been slightly more unsettling, bringing the audience closer to what Spock and his crew are likely feeling about their momentary drinking buddies, instead of the much more casual feel we got from Klingons who look just like our old friends from DS9. These guys are still dangerous aliens whose friendliness is tenuous and temporary; they would literally eat Spock if circumstances were slightly different. We shouldn't forget that.

I thought it was all a bit confusing - it was introduced with no explanation, which felt like it was setting up some big reveal that never came.

I like the, as you say, Giger-esque design but felt it was such a departure that they may as well have introduced a new species.

I very much enjoyed that in season one, each Klingon house had their own uniform, and customs. In the TNG era there is a uniformity to the Klingons, which flattens them to monoculture. Even the simple touches of having House Mo’Kai engage in facial scarification, or House Kor wear war paint implies an expansion to their culture that makes me far more interested in them.

Also, I’ve always enjoyed the scheming Klingons, like the ones we see in TOS, or the Duras Sisters, so Kol really appealed to me as an antagonist.

The new prosthetic seemed like a natural progression of what we saw from TOS, to TMP, to “The Search for Spock” and TNG. I do think the decision to make them all bald in season one was a miss, but it’s otherwise a good design that effectively communicates the ferocity the species is supposed to have.

I wonder if they wanted them to all be bald if it wouldn’t have made more sense to have T’Kuvma’s followers be bald, and the others that arrive after he lights the beacon engage in tonsure once T’Kuvma becomes a martyr.

Oh, and the elongated craniums on the women was also an odd choice that I’m glad was walked back for season two.

I'm going to be honest, Klingons in the TNG era always felt too goofy to me. They weren't a proud warrior culture so much as borderline clownish space vikings who spent more time getting drunk than actually conquering anything. A redesign and change in how their culture(s) present on screen was welcome for me, and I think Discovery did a great job. I even liked the way they recontextualized the Klingon language, to make it sound more alien and more threataning than the staccato, oft-mispronounced mess that we got in the TNG era.

That said, I also think there was a missed opportunity with them. For a long time, I've had a head canon of the different looks of Klingons throughout all of the eras could be chalked up to these all being distinct peoples from within the Klingon Empire. It stands to reason that over a long enough time scale, an empier spanning multiple stars would start to consider people not originally from their homeworld "Klingon," even if they might be genetically different. I always thought it would be cool if the TOS smooth forehead Klingons were actually just one species that were culturally Klingon, where the Worf-type were another, and the General Chang type was yet another. It would provide a way to smooth over the aeshetic differences with an in-universe explanation that doesn't require any retconning except for a handful of episodes from ENT that die-hards didn't like anyway.

But oh, well. One can dream.

No.

If STD wanted to do something different, then they should have gone 300 years into the future beyond TNG and done something different.

Since Enterprise I have hated that all the new Trek properties have been prequels. The people who are now responsible for Trek either do not trust themselves enough to come up with original ideas or (more likely) have a significant disdain for the property to begin with and don't want to come up with original ideas, for fear of being taken for someone who might do such a thing (ie: nerds).

Thus they can push the property forward supposedly building on the ideas of others, but in order to foist the appearance of originality on everybody in the face of this, they drastically - and without explanation - alter fundamental aspects of the source material. They do this apparently not imagining there will be a backlash. The inability to imagine a backlash can only come from their own personal dislike for the source material. They either find it so goofy and ridiculous that they can't imagine anyone else would be passionate about it - or (again, more likely) they find themselves so superior to the source material in their own minds that no matter what they do, they are certain it will be seen as an improvement. Even if it isn't seen that way, they don't care, again, because fucking nerds.

Klingons are a thing. Extremely well developed, lots of interesting lore. OK, so these new aliens are more scary. They're more dangerous. They're more like warriors. Fine. Put them on a different planet 300 years in the future and stop shitting on the past. Same thing with their stupid fucking mushroom drive hooked up to tardigrade nipples.

Edit: I feel like I should mention, I like SNW even though it's a prequel. Look what it did: changed an alien species (the Gorn) that we really don't know much about - smart(er)!

Klingons have had two totally consistent design elements from TOS all the way through Into Darkness that DSC didn't incorporate. The first is that the majority are fairly hairy, and the second is that their tech is very industrial and bare-bones looking. I can totally buy Klingon factions that stray from either of those things, such as a group that shaves their heads or has more elaborate tech, but the entire species being that way doesn't work. The facial redesign could have worked, but ultimately the masks were too thick for anyone to emote in and they hindered the acting. Season 2 thinning the masks a bit and adding hair was a huge improvement and showed that the concept could work, but the organic looking tech just doesn't do it for me at all as the predominant look in the empire.

Overall, I get what they were going for, but they lost what little consistent design language the Klingons had and it just did not work for me at all.

Most of this reasoning is irrelevant to me simply because I don't view each show as seperate. I watch DIS s1 and see this Klingons and can't help but think "so what about Kang, Kor, or Koloth? How do they look right now?"

It doesn't matter how cool or scary these new klingons look, they have four nostrils and elongated heads when before they were more like buff humans with ridges. That's irreconcilable to me, regardless of how the actual aesthetic makes me feel when I watch an episode.

Taking it at face value, the Klingons looked like TNG, then they lost ridges, then regained them with even more than we'd ever seen before, then they lose them, then they go back to TNG? That's annoying.

The Bird of Prey design looks... imposing. The Armor, despite being very impractical, looks good. The Alien Race is well-designed, but it's not what I would think Klingon would be. But yeah I kind of like how they're portrayed, as a serious threat instead of some goofy alcohol-addicted space Vikings with a kind-of interesting way of life.

Discovery was my "gateway" Trek which led to me watching everything else (except TOS yet) so I had no expectations or anything for what Klingons should look like.

So I didn't think they looked "off" until I started watching the TNG era shows. Even then, I just attributed it to artistic differences.

All that said, I do like how they refined what they did in DSC for SNW. Those look more like TNG but upgraded

I thought those early Klingons were super weird and scary because they were just so alien.

Absolutely. And the costuming choices they made, and the different aesthetic approaches to each Great House, show an amazing amount of thought and care. They're one big, scary, alien, fractured family.

The only huge issue I had with them was their makeup was so thick the actors clearly struggled to act through it. Contrast to such expressive Klingons such as Kor, Gowron and Martok which was very difficult to do when you can barely move your face.

If that hadn't hamstrung the actors so much, I think they would have been more enjoyable than people found them.

I dug 'em. It was a good experiment in pushing Trek's aliens beyond a forehead and an accent.

I thoroughly enjoy most everything about DSC Klingons. With their appearance, I didn't like or dislike their look when I first saw it so much as I was surprised. Klingons have a history of looking very different throughout Star Trek. I've rewatched DSC so many times, I'm used to how the Klingons look. However, I absolutely love the depiction of Klingon society. I still marvel at the Klingon armor and sets. The dichotomy of such a combative society and the intricate beauty of their ships, armor, everything. Their artistry goes beyond simple functionality. I think it adds depth to the Klingons.

I like the idea of klingons being very diverse.

I don't mind that they tried. And tried to link them with TOS and later Klingons. I just thought the makeup was too heavy. You never really got any memorable Klingon character faces. And I'm just taking about their faces. I enjoyed their costumes and ships.

I'm not really a fan of "it only looks overdesigned cause its supposed to be alien to you!" That they did with early Disco klingons and have done so far with SNW's Gorn. That line of thinking works for one off antagonists like V'ger, but these aliens are effectively supposed to be recurring characters and and making them and thier ships big balls of (sometimes asymmetric) noise means they all just start looking uniformly chaotic on top of being hard to replicate and recognize outside watching the show.

I rather liked it, and the more alien take on them, but I can also see why people didn't.

Part of the issue is probably that Discovery changed them too much. Previous alterations to the Klingons tended to be one thing at a time, except for the TOS films, but even they kept some things the same, like their technology.

Discovery went with a bit more of a complete overhaul, with massive changes to the language (following the pronunciation guide more closely), and alterations for both their technology, and the Klingons themselves, which might have been a bit jarring for most, especially when people were expecting more of a settled look for the TNG/TMP Klingons.

You do have the visual changes for the Klingon Empire in the Kelvin films, but that gets excused as it being part of another timeline, hence all the differences.

Things like the Klingon cleave ship, and the T'Kuvma are massive changes from what people are used to when it comes to Klingons. Klingon technology previously tended to be birds of prey that cloaked and shot energy bullets/torpedoes, not cloaked ship-breakers that used ramming speed as their main vector of attack, and Klingon supremacists didn't really exist like that. The closest we had to something like that was Worf, who was much closer to a Klingon purist/fanatic than a supremacist.

Although I personally feel that there was a missed opportunity not interspersing things with the various other Klingon designs of the time. Having a supremacist faction within the Klingon Empire, with massive visual changes (maybe due to overcompensating for Enterprise's Augment Virus?), could have been an interesting way to add depth to the Klingons, and the Empire.

Especially if that diversity of thinking between the Houses is/was one of the strengths of the Empire. Each House was more like a separate power, and they simply collaborated under the banner of the Empire.
