A math genius works as a janitor at MIT, unable to overcome his difficult upbringing. The premise of this film is ludicrous. It really requires suspension of belief to buy that Damon, who never attended college, has become a genius by reading books. The pretentious and manipulative script by Damon and Afleck really reaches: not only can he do complex math problems, but he can hold his own with anyone when discussing politics, philosophy, economics, literature, and history. We are supposed to root for Damon, but he's such an arrogant jerk that one roots for someone to punch him out. Williams is fine as a psychologist, but it's a role he has played a number of times. Driver does well as Damon's needy girlfriend.
