Artistically, Prince’s semi-autobiographical “Purple Rain” (1984) isn’t any worse than Eminem’s hometown-kid-gets-his-break film “Eight Mile” and the music is far superior, even if some of Prince’s performances are head-scratchingly weird. Speaking of which, the eye shadow, studded jackets, teased hair and pirate shirts kinda weirded me out when I was a 1980s high schooler and I don’t think it’s gotten any different with age. But who cares what I think about fashion? This is a 111-minute music video designed to appeal to Prince devotees and sell records (for Prince, Apollonia, The Time, etc.). It did a good job of it.
