The Pursuit of Happyness is really bad. Will Smith's inspirational moment is going to the New York Stock Exchange and seeing all the happy rich guys in suits walking around, and wanting to be like them. Having to do stuff like brown-nose executives, sleep in train station bathrooms and pull his son out of daycare due to lack of money are presented not as flaws of the system but evidence of Smith's smart bootstraps-oriented thinking. This movie is the Mein Kampf of liberalism.
The biggest difference if I recall correctly, is that in the book Forest ends up homeless with Lt. Dan. Thats why hes on the bench talking to people. He's not a millionaire "great man" boot straps guy.
