I feel that it is time to reconsider some of old comedies about the ghetto. Nothing improves mood more than the reality of the stories in these films. But  there are many moments that are worth thinking about.
"Finally, this movies that proves that Justice isn't always Poetic, Jungle Fever isn't always pretty, and Higher Learning can be a waste of time." - Marlon Wayans.
I would also like to recommend a great serial film on this theme about a famous comedian Chris Rock, but rather his childhood. "Everybody Hates Chris!"
