I was surprised there wasn't one. I had always heard about this movie but didn't really have any interest in it. I still didn't but one of my friends is obsessed with Prince and wanted me to watch the movie with her. I thought it was awful. So cheesy. Solid music but the writing and acting are just plain bad. And it seems to go on forever. Just when you think it's the final performance there's yet another song. I think there were 4 to close out the film. It just kept going.
Anyway, I don't know what I'd rate it. It's bad but at times kind of entertaining in a trashy way.
