That's why the real-life movie disappointed Avatar fans (and let's just be clear: this series has nothing to do with huge blue alien men). There is too much life in the series to crop it down and fit it into a little box of a movie. You just can't capture all the emotion, the humor, the beauty, the epic grandeur combined with moments of raw heartache or fun impishness in a two-hour film. Sure, you can duplicate special effects and find look-alike actors who can lay down some wicked martial arts moves, but the TV show is about so much more. I can't completely disrespect what Hollywood tried to do with its movie adaptation: The Last Airbender. As a stand-alone movie for the uninformed, non-Avatar-watcher, it was stunning in its own way.
But let me put it this way. I just sat through two hours of the animated finale, as long as a full-length feature film, and enjoyed it more than I could enjoy any movie out there. That's because there's so much depth and history to the characters, and a movie just can't set that up and get it right. Also, wow, the music of the ending was just perfect.
So, I haven't given any actual details about the show because I wouldn't want to spoil a minute for anyone. You can stream the show on Netflix, but if you want it for your own collection, it would be money well spent.
Five stars for absolutely everything.
