If you try to hold it against original, itll feel clunky and weird-- but still better than that movie from years ago.
All the bending CGI is clearly done on green screens, because all water-benders are looking NOT at what they're doing, but juuuuuust slightly off-course to some pre-ordained cue card. Its very distracting once you notice it, (sorry if i made you notice it, thats my B)
Characters are all seemingly rushed, and the actors are trying real hard to emulate their designated role.. but its just weird. They FLY through the "fire nation killed the air benders" nonsense, and skipped the avatar test stuff for all who care-- they just kind of finger point aang into power based on his physical/bending prowess. Idk man, ill chew on it some more later, but count me out of season 2.
