Ken Russell's insane adaptation of The Who's rock opera masterpiece Tommy is one of the most insane musicals to come out of the 70's and 80's, and that's saying a lot, because there were a lot of them. The Apple, Sgt. Pepper's Lonely Hearts Club Band, Phantom of the Paradise, just to name a few. Some of these kinds of movies were genuinely good, but some were just not good. This one is sort of fascinating in its badness, because it's not a good movie, or a good musical, per se, but it's fun to watch the madness ensue. While Quadrophenia is a much better movie than Tommy, they're both pretty different films by comparison. This one has a more notable cast though: Roger Daltrey, Ann-Margaret, Oliver Reed, Jack Nicholson, Elton John, Eric Clapton, Tina Turner, and The Who, of course. Like I said, this isn't really a good movie, but it's a fascinating movie to watch. I enjoyed it, but more by its WTF factor.
