I have to agree with Nick on the things he didn't like, as I thoght the same thing at pretty much all of them. It would've made much more sense for Amon to burn himself, as he as the intelligent person he appeared to be, shouldnt've expected a positive outcome with a silly make-up trick like that. It pretty much ruined his all plan, though oh well. He did turn out to be a coward at the end anyways.
With Korra getting her bending back being the main goal for season 2, it would be quite like AtLA's first book, since the only kind of bending she would be able to use was airbending, which is something I'd have liked to see. But oh well, that would've been quite predictable though, so at least now we have something to look forward to, rather than already knowing what the next season would be about. Really looking forward to it.
