Music ruined it.
They really blew it with the soundtrack on this picture. I know some Clapton fanboys will defend it, but deep down you all know just how badly it dates this otherwise decent movie. There's plenty of other movies from that came out at the start of the 90s that are still as fresh as ever, but Rush is not one of them, thanks to the awful soundtrack.
Music is supposed to enhance the tone of a picture, but playing obnoxiously loud, screeching electric guitar over an emotionally charged drug scene is really amateurish.
A lesson to take away from this. If you want an original soundtrack, use a professional movie score composer. Clapton may be great guitarist and song writer, but a movie score composer that does not make.
