They dont call em blaxploitation movies anymore. they are called Tyler perry movies
You are absolutely right about that.
For the list of good black directors
Carl Franklin directed 'One False Move' a very good movie. 'Devil in a Blue Dress' w/ Denzel, pretty good. 'High Crimes' and 'Out of Time', both better than decent. Some of his movies have few blacks because the are novel based.
Forest Whitaker is a good director and great actor of course.
F. Gary Gray is good.
Sidney Poitier great actor to say the least and good film director,
1972 Buck and the Preacher, one of my favorite westerns
1973 A Warm December,good black love story thats right I said it!
1974 Uptown Saturday Night, good and funny
1975 Let's Do it Again, ditto
1977 A Piece of the Action, ditto
1980 Stir Crazy, ditto
