Just saw this tonight. A very, very ambitious movie. There's a lot of cool stuff happening, but its reach definitely sometimes exceeds its grasp (in a way, this is somewhat thematically appropriate). Plenty of fantastic set pieces and a good amount of compelling drama, but things tended to get cringe-worthy pretty quickly whenever anyone started talking "science." I'm a pretty huge science nerd, so these moments took me out of the film. I should definitely say that I think most of you will be pleasantly surprised with Zimmer's score. Refreshingly different from the bombast for which he's famous. Possibly my favorite work of his since The Thin Red Line.
