I won't defend 3 Strikes or Waist Deep, but I enjoyed Kingdom Come and I didn't find anything overtly stereotypical about Breakin' All The Rules. If anything, that could have easily been a film with an all white cast and nothing would have had to be changed beyond that. There was nothing that made that film stereotypically black, about the only black thing about it was the characters' skin. None of the characters live in what you might consider "the ghetto"(and I wish people would realize a ghetto can be ANY impoverished community regardless of race), Jamie Foxx and Moris Chessnut's characters working in publishing, and Gabrielle Union's character is a medical professional.
And as a black man who's gone to black barbershops the better part of twenty years, I'd say the movie Barbershop is pretty accurate in terms of how discussions go down, and all the types of people who find work there. There's some exaggeration for comedic value, i.e. Cedric's character, but even he had his moment where he had something meaningful to say.
