I have to say that i'm not aware of other Parr's films but this one is truly funny as hell.
He graped all the stereotypes about black people and used it in a hilarious way. This is what we call in Greece "To knowing myself". The acting is exceptional for this kind of movie and the characters has been treated with absolute care one by one. It's a well structured comedy and all the quotes and impersonations of other familiar people are just brilliant and hilarious.
The impersonation of D.Washington from the movie "Trainign Day" was one of the greatest scenes in the film. Same for the actress who's playing the pageant girl, i couldn't breath cause of the laughs. But as i said above, the thing that does this film such a great comedy is Rus. Parr's brilliant way to use all the stereotypes into a self-sarcastic way.
Don't miss. I don't know if i should recommend to you to go to the theaters but definitely get it on DVD. It's just a great comedy for a long time now. Enjoy it.
