Avatar: The Last Airbender

One of the best kids' shows ever, period. The in-depth world-building, appealing characters, innovative action scenes, character-based humor, surprisingly mature themes, and amazing animation combine to create a show that appeals just as much to adults as to kids, maybe more so.

A refreshing blast of beautiful animation, terrific character development, kick-ass magic-filled action scenes, a rich and fascinating mythology that is revealed at a perfect pace throughout the series, and a story so satisfying and so well-told over 61 episodes that even big grown-up TV series should study and learn from it how to plan out a story bible in advance and pace that story out just right. Terrific. Why can't any other animated kids shows - I mean, like, a single one - be this good?

A Nickelodeon show with as much character development, world-building, intense action scenes, moral complexity, dramatic tension and emotional maturity to rival the best of HBO. Who woulda thunk? The show blew my expectations out of the water my first watch-through and continues to impress on subsequent viewings. Not just the best kid's show I've ever seen, but one of the best dramas, period.

Don't let the first few episodes fool you. This is a show with characters that grow and develop, a story that is equal parts smart and sweet, and action and adventure for all.

Surprisingly well-written cartoon. Obviously takes cues from Japanese anime, but does well enough to stand on its own merits. One gripe I had would be the main character being kind of a wimpy idiot (which I guess is understandable considering his age) also some episodes were hit-and-miss, but that's about it.

A strong contender for the best Western animated program ever (at least in the action-adventure genre) due to its surprisingly in-depth themes and world-building; 'The Last Airbender' is a melting pot of tried and true fantasy tropes and Eastern culture, resulting in a show that appeals just as much to adult audiences as it does to children.

Some of the best children's television around.

A very good show that initially failed to realize its audience, but makes up for it in latter seasons by striking a perfect balance of levity and depth. The perfect kind of show for young adults to bridge the gap to more mature material, and a pretty good show for adults in its own right, assuming they don't act like watching a cartoon makes them gay homos or something. REWATCH: This is superb.

A cartoon that depicts what is possible when their creators have genuine care for their craft. World building, animation, story, and characters are top tier.

S1 62. S2 67. S3 65. no argument for it being the best cartoon ever, it's too childish. i hope people mostly think they cuz they were young/nostalgia. zuko was immediately telegraphed but often done well, especially with his uncle. aang had too many moral dilemmas condensed into 1 episode of learning and a moral lmao. humor the most childish and meh. some dope martial arts/philosophy/lore but usually rushed or a bit too simple. S3 even had filler lol. ending romance and nuff other things rushed
