Saw it in 3D, loved it. The story is right up my alley, its something I've always believed in and felt that everything on this planet is connected (reefs prove it). I feel it whenever I go into the forest... there is energy there.
The story was extremely similar to the cartoon movie Fern Gully (if anyone remembers that one as a child!?). A guy employed as a logger finds himself shrunk into a fairy, and falls in love with a fairy girl trying to save her forest from the loggers. The forest is magical and everything is connected, with a guardian spirit watching over everything. Love that movie, too.
Oh and Princess Mononoke is another one that people should watch if they liked the story in Avatar. Its anime, and I'm not a huge fan, but its beautifully done.
All in all I might just go see it again in the theater (this is one that I wont bother downloading).
