It's Blaxploitation, but that's not the problem. You either like that genre or you don't. Essentially, every comedy with black people in it is Blaxploitation to some degree. See, for example, anything Tyler Perry has ever made. The problem is the movie is formulaic as hell. Richard Pryer gets Fred Williamson into trouble, then the song "Adios Amigo" starts playing, and Pryer escapes, leaving Williamson to fend for himself. They reunite later, and the formula repeats over again. That's the movie. Is it funny? Depends on if you like the comedic chemistry between Pryer's high jinks and Williamson's straight man.
