In general I think Purple Rain is one of those movies that if not for the music, the show is nothing. But who knows. Prince does try to tell the story about his trip to superstardom. There's only a way to the top from his early days in Minneapolis.
Throughout the movie we hear a nice soundtrack. Not just the songs that were from the soundtrack album (which was #1 for 24 weeks on Billboard's Pop Album chart), but songs from Morris Day and Apollonia. With every movie comes a story. Prince is known as 'The Kid' who spends most of his time away from home (mostly because of his abusive father), rehearsing during the day and performing at night with his backing band, The Revolution. But he is also competing with another top draw at the club (First Avenue in Minneapolis, which still exists): Morris Day (playing himself).
Some coolness intertwined here and there, such as Prince's motorcycle ride scene as he takes Apollonia to 'Lake Minnetonka', or so she thinks! I recommend this for any Prince fan, and definitely buy the soundtrack. It's always great to see someone work his way through everything, no matter what. Some may find the story too dark, or too soft, depending on whatever way to look at it.
My rating: 6 out of 10
