Slow and boring movie about a delusional mathematician which dont focus on the reality in the portrayed persons works. I dont like it because i dont like to look at a disturbed person and his experiences. If you want to see a real nice and fun movie, see scary movie 2 or something really funny like "not another teen movie". However, i dont see how one can try to go into this persons mind, this is just a quick glance at something of course more complex and involved than its room to place in a one and a half hour movie. Instead, you should study some psychology, and in that case use this movie for some kind of acknowledgment of your already learned knowledge. The mathematic aspect is, as expected, strongly simplified, and a kind of a crack kids high in the cloud fantasy. Why dont we see more of the interesting works of this man? Probably because one of two reasons. We already have one reason; the time aspect. This is acceptable, if you dont count on getting the priorities straight, because the obvious time limit of a long film. The other possibly reason is because the film makers is thinking not many people would be interested in a film, harrowing about boring mathematical problems. If that is true or not, can of course be discussed. I however believe its perfectly a necessary component in this kind of movie.
