Altered carbon, the whole resleeving of a person into another body. Made it seem like they could have done loads of stories in that universe with different actors.
Shame they only made one series.

Heroes. First season was great, if they kept the concept of each season being a be set of people with special powers they could have made endless seasons and stories.

There was a miniseries on the SyFy channel called "Ascension" that, ostensibly, had the premise of being a murder mystery set on a massive generation ship launched at the height of the Cold War, which sounded fun in theory. 1960s Space Race technology, generations raised on Red Scare values despite the Soviet Union being a distant memory in every sense, a bunch of already-paranoid people trapped with a murderer with safety literally decades away - seems like there's a lot of room for a story there, right? Well, if the words "miniseries on the SyFy Channel" didn't tip you off...

So anyway, a show that actually stuck to that premise would probably make for a pretty compelling yarn.

The original plan for the second season of Stranger Things was supposed to be a separate story with a few connections to the first season, each season being a different story and cast. I would have loved to see that actually happen, since the second season lost my interest a couple episodes in.

Altered Carbon.

Season 1 was GREAT. Season 2 wasnt.

They fucked up the most important thing possible with a series changing actors for the same character. YOU NEED TO MAKE US LOVE THE CHARACTER NOT THE ACTOR. They didnt lay in a bunch of physical gestures, catchphrases, signature moves, character traits. Nothing that made be believe Anthony Mackie was the same guy as Joel Kinnaman.

I would love to watch something like The Walking Dead, but more chill. More to do with building a community, and re-imagining society. Surviving the zombies would be a topic, of course, but without all the extra evilness of the remaining humans.

And episodes that don't force me to increase my TV's brightness to the max.

Rings of Power. I really wanted it to love it.

Sword art online. Drop the rape and incest beats entirely. It had potential to be a great anime about the meaning of life and instead largely ignored that possibility.

Applies to lots of anime. I've been really disappointed by Dragon Maid. Lots of LGBT+-themed anime in general, I'd want to see them remade in an environment that lets them be more explicit about the LGBT+ themes instead of dancing around the issue with that "just really really good friends" stuff (or just cancelled before the story gets there).

I want a faithful adaptation of Asimov's Foundation, where it's the 1940s in space like in the novels.

Guy gets to planet, immediately buys a physical newspaper with physical cash. Takes a taxi cab. Everyone smokes constantly. Space soldiers are bribed with dishwashers and fridges, computers barely exist. Every desk has an integrated atomic ashtray to vaporise cigarette butts. Scientists carry bulky pocket calculators.

Please remake and give proper endings to warehouse 13 and utopia

Heroes had so much going for it before the writers strike, the premise of that show felt so good then it just got bad.

Revolution.

Almost Human

The Starlost needs a remake. Great premise, dollar store execution.

What they wanted:

Foreseeing the destruction of Earth, humanity builds a multi-generational starship called Earthship Ark, 50 miles (80 km) wide and 200 miles (320 km) long. The ship contains dozens of biospheres, each kilometres across and housing people of different cultures. Their goal is to find and seed a new world of a distant star.

In 2385, more than 100 years into the voyage, an unexplained accident occurs, and the ship goes into emergency mode in which each biosphere is sealed off from the others.

Centuries after its original launch, most of the descendants of the original crew and colonists are unaware that they are even aboard a spaceship.

How it went:

Unable to sell The Starlost for prime time, [20th Century Fox television producer Robert] Kline decided to pursue a low budget approach and produce it for syndication. By May, Kline had sold the idea to 48 NBC stations and the Canadian CTV network.

Originally, the show was to be filmed with a special effects camera system developed by Doug Trumbull called Magicam. ... The technology did not work reliably, however. In the end, simple blue screen effects were used, which forced static camera shots. ... The failure of the Magicam system was a major blow, as the Canadian studio space that had been rented was too small to build the required sets. In the end, partial sets were built, but the lack of space hampered production.

As the filming went on, [the writer Harlan] Ellison grew disenchanted with the budget cuts, details that were changed, and what he characterized as a progressive dumbing down of the story. ... Ellison broke with the project before the airing of its first episode.

Star Trek Voyager. I don't think I need to explain further, we all have the same ideas.

Looks like the upcoming game will do the fixing though, so that's good.

The Expanse. Or at least an ending to the Expanse that we have. I loved those books so much and they did the series so dirty.

I do accept that the last (I think it was) 2 books don't translate to film very well but at least they could have tried!

Space Force, really good cast and concept but I wish they better writing.

Lost Girl. I was so in for a succubus themed mystery drama type affair, but I couldn't maintain interest through the second season. It was slow and awkwardly written, but I think the subject is solid and it could have been done a lot better.

Give me Lucifer with a Succubus lead, come on TV execs

Wayward Pines. Great concept but then they basically explained everything in a handful of episodes and took the whole mystery out of it. Also, some of the acting was terrible.

In some ways, Silo is its spiritual successor but without

Another one I’d like to see redone or relaunched, West World. Incredible first season. Nothing left in the writer’s tank after that. That first season was so good though that I don’t think it can be rebooted.

Battlestar Galactica. How can anyone mess up a 70's disco sci fi?

I'd love to see an un-bungled True Detective again.

Halo.

Just make it animated, and don't add anything.

It's almost impressive how bad they fucked this up...

You know what, I already did one but I'm gonna do another one: Lovecraft Country.

First episode did just about everything you'd want out of a Jim Crow-era supernatural horror road trip mystery. Felt like they really had a handle on the whole "fear of the unknown and incomprehensible" vibe that you don't see done well very often, the cast had great chemistry, and the whole theme of "the real incomprehensible eldritch abomination threatening human sanity is racism" was executed flawlessly. They walked a very fine tightrope between homage and condemnation of Lovecraft's whole... deal and nailed it in one.

And then the main mystery is resolved by the second episode and the whole thing devolves into a very uneven anthology of psychic snakes and angry ghosts and like, Nazi wizards worshipping what I think was just the regular devil and overall very known and comprehensible horrors that didn't really hold my attention for long enough to see if they even tried to tie them all together.

Man, all I wanted was a long-form cosmic horror story wrapped in a character-driven prestige TV period drama with some biting social commentary that doesn't suck. They don't make a lot of those!

Dead Like Me And the Dark Crystal show needed the ending it deserved.

Swamp Thing was so much worse than it could have been. Gothic horror, beauty and the beast, cosmic terror, body horror, monster of the week serial but it's a bigger monster hunting monsters, etc it's got all these interesting angles and they ended up focusing on none of them.
