LOK for sure. It's different in a lot of ways, but from a production standpoint, I believe they were working season to season, so it was harder to plan out a coherent multi season story a la the original ATLA.

I found the live action unbearable within the first few minutes, but YMMV.

Can't say I read graphic novels, but there are some YouTubers who have adapted some of them into graphic novel videos? Once you get used to the new voice actors, they're actually kind of enjoyable, at least once I've seen.

The novels! The novels are great! They're way better than the comics,.

LoK is awesome, don't listen to anyone who tells you otherwise. Watch it in HD with headphones, its gorgeous.

I can recommend similar "western anime" shows, as we have some that are clearly pay homage to Avatar.

There are a number of graphic novels that continue the story, so you can kinda watch the gaang grow up. The first series, I believe, is called The Search, and it's about finding Zuko's mom. There are also a ton of spinoff novels about the other avatars if you want more lore.

There isn't an animated continuation of Aang's story. The only other animated series in the Avatar universe is Korra, the avatar that follows Aang.

Korra takes the story through some very controversial changes, and production was frought with difficulties thanks to Nickelodeon constantly changing their minds on what they wanted. Season two is widely seen as the worst in the series by some distance, but season 3 redeemed it somewhat.

It's worth a watch for sure, just don't expect it to live up to the magic of the original.

Korra is great, it had some issues from Nickeoldean that reduced its success. Basically they had no idea if there was going to be a season 2 or 3, so it was written that way. 3 and 4 are more connected.

There are 3 books series, each about Kyoshi, Yangchen and Roku (released in that order). Good books.

There are a lot of graphic novels for both Aang and Korra. I know they are free on webtoon and Hoopla (many libraries offer free acess to hoopla). (Webtoon doesn't have all of them yet, they've been regularly posting in the past year)

Netflix ATLA is a live acation remake made by different people. General option is meh, not as bad as the movie.

The movie is probably the worst movie released by a major studio, even by today's Netflix series wrecking standards.

I don't get the controversy around Korra. I thought it was brilliant. I assume it's because people wanted more of the Aang Gaang and it was something different (and maybe a little bit because it was a girl this time).

Someone answered already, but you can check out Korra next. I haven't personally watched it, and it seems to be a subject of contention in the fandom.

Netflix's live action series is a watered down remake of the animated ATLA. It was... Fine?

What did you think of ATLA?

You could do TLOK, but I'd say it's less a continuation of ATLA, but more like it's own thing.

I really liked Legend of Korra, personally. Not as much as ATLA, mind you.

Like others said, the story isn't really a continuation of ATLA, it just occurs in the same universe. You do see a little bit of how the characters from ATLA few up and their own offspring, but it's not really the focus.

It reminds me a little of Kevin Smith movies. They all happen in the same world, but they're all their own thing.

One thing I didn't like about Korra was that each season seemed kind of self-contained. ATLA had a better defined arc between the seasons in the whole series. I think they did that in case they got cancelled and they didn't want to end on a cliffhanger, so I can appreciate that.

I liked exploring the focus of a more mature avatar growing into her role.

I've never watched the live action series, though. I'm a little hesitant after seeing the movie...

Personally, I would watch Korra first then get into the live action series, simply due to the fact that watching the same story twice in a row seems like a bit of a drag.
