A perfectly entertaining action movie with a fun sci-fi twist. I'm amazed I'd never heard of this before or been recommended it. I only wish the main concept wasn't spoiled for me before I saw it. Jake Gyllenhaal fits his role well & everyone else is fine but just kind of 'there.' You can't think too hard about the concept if you're going to enjoy it though; that being said the ending goes for happy instead of realistic and brings up all sorts of questions that the movie doesn't care to answer. Overall a great, relatively tame, 'Mission Impossible' type vibe & does well to please the whole crowd.
