Definitely worth watching, but not quite as good as A:TLA. Reasons include a far more interesting villain than Ozai, way better fighting -in fact probably THE best looking combat in all of animation, a couple of very awesome characters mixed in that easily rival those of the original, flash backs to the original characters, a much darker story, and overall a very high level of storytelling. That this isn't as good as A:TLA does not mean this is a failure, far from it. It just goes to show how incredible the original really was.
