There is no other film like this. Made with amateur directors, actors, and filmmakers, this is really 3 films in 1: a concert performance film (superlative, amazing), really awful MST3K hilarious acting plus intentional comedy that is hilarious (Morris Day stuff), and a domestic violence/introspective drama/romance.

It's something of a mess, but it's a beautiful mess. It's also the most wildly entertaining film I've seen in memory. I never wanted to stop watching it. In fact, I immediately bought a book on its making, "Let's Go Crazy: Prince in the making of Purple Rain" by Alan Light. I am dying to know how this insane thing (which made a fortune, made Prince a star, and made him the first artist to have the #1 single, #1 album, and #1 film, all at once).
