Saw the movie today. It wasn't too bad, but I guess you could say it falls a little bit from "WALL-E Syndrome" where the majority of the movie is spent with characters that don't talk... since they're monkeys. 😛
Although, I think my viewing experience was a bit marred by the theater failing at sound checks... pretty bad when I pay a premium price to even go there. :\ The audio channels seemed to be mixed up, which bothers me as I'm used to hearing voices from a center channel (in front of you) and all voices came from the left. All music and sound effects came from the center and nothing came from the right.
EDIT:
I can barely remember the original movies, but I think there were a lot of references to some of the apes from them? I'm not really sure, but they seemed to focus on a few things often that I assume are references. 😛
