I just finished
Avatar: The Last Airbender. I wouldn't say it never falters, but there's quite a lot of really good stuff in it. Imaginative and funny. I'd say it's definitely worth watching. There was some heavy stuff in it which I didn't feel was too dumbed down for children. You kind of have to watch the whole thing, though. It really picked up in Book 2. I'm sad that
Mako passed away before Book 3. They got a decent imitation for his voice, but the delivery just wasn't the same. Anyway, I was happy with the whole thing. I was pretty skeptical that I'd like it.
