I liked it. I generally like Ang Lee movies. This has some really beautiful work in it and the 3D is well used (subtle when it should be, deeper for good effect.) There were a couple of parts that pushed me out of the story with over earnestness, but very very good. I have not read the book, but got some idea of it from others after seeing the movie, and having the director visit for a Q&A at my work moderated by the director of Rise of the Guardians who used to story board for Ang Lee. Cool day.
He really talked about what I love about his movies, that he insists on leaving room for the viewer to decide just what a movie is about. Most of the questions posed to him were about how he manages to be so dead on in depicting other cultures different to his own, and his answer was that he listens to his advisors. Such a non-Hollywood-like answer.
