It's not even that. Sometimes it just stifles innovation and black directors are made to make movies that they may not like. Not every black director wants to make "black" movies. I like mysteries/suspenses. One of the best movies I have seen is Blowout with John Travolta. I know of other great mysteries but I think this is De Palma at his finest. If yound cat comes along and wants to make flicks they may just tell him to make another TP movie, Spike Lee movie or ganster flick like some years back.
I have nothing against him. He has his niché market. That is all good. His movies are shit just as most movies tend to be shit, but that is Hollywood. At least he his making movies and black actors are working, but his writing is weak. The characters aren't challenging so actors aren't able to showcase their ability in his work.
Trust me I FEEL you. But that is not Tyler Perry's fault.

What is he supposed to do about that. I mean damn the man has HIS OWN MOVIE STUDIO and is keeping several existing black workers acting.......and breaking in new ones. Niggas still aint happy.
Tyler nor any other singluar black person can represent or save the entire black community.
