I would have preferred if it were more serious. There are moments in the movie that felt like should have been more meaningful but the quirky comedy of it took away from that. However, that WAS the intentional tone of it, and I'll admit that it makes the story elements more palatable. It can be very difficult to watch things about the history of racial injustice in this country, and by making it irreverently comedic, it makes it easier to watch. I'm not sure if that's a good thing or a bad thing though. It also ended kind of abruptly.
