After seeing The Kids Are Alright, we got out the film Tommy as well.
It is interesting, but not really fun. Ken Russell's direction is so over the top and bizarre that the film is really an exercise in trying to work out what the fuck he is trying to show you. Not really entertainment at all.
Also, the music isn't as good as the album.
On the plus side, the cameos from Eric Clapton, Tina Turner and Elton John are hilarious. In fact, there are a whole lot of funny scenes in there, in between the being confused.
