For me, the movie rates right up there with Blade Runner, the Godfather and Raiders of the Lost Ark.; Mel Brooks made the perfect, most politically incorrect satire ever made.
NO ONE can even start to touch it!
And yes, if you made a movie that is so crass and brazen these days, you would have Al Sharpton and his ilk stirring up riots, Media backlash, etc.
Interesting factoid: The script was co-written by Richard Prior.
