Under the Cherry Moon (Prince's other movie) is such a bad film, everything from the pacing (it sure did seem like a lot was going on for all of that to be happening in what seems like 5 days), to the one-dimensional characterization of the supporting characters, to how they decided to create some ambiguous time period which is some strange combo of the 20's, 30's, early 60's and 80's, etc.. It is such a bad movie, but I love it to death. :D
For what it's worth, the "WRECKA STOW" bit is classic, the score is one of the best I've ever heard and the cinematography is quite beautiful.
