I thought the movie was interesting visually, but thats about it. The songs are cool, but a lot of them were cut from the movie.
If you ever have a chance, go see the stage production. Its too awsome for words, and very powerful. A lot of political and social issues were touched upon that were dropped from the movie. Basicly, the movie is nothing like the original play - the story was completely changed, and just kept the characters and some of the music, and a vague semblance of the plot.
Nevertheless, the movie is still fun to watch - I can just be an anal retentive purist at times
