I saw it in London too a while ago. Must have been about... 3-4 years ago? Anyhow, I saw the movie and it was pretty good. If you are comparing it to the musical, you'll be slightly disappointed, but if you think of it as a musical-movie, I think it does really well :) I wasn't too fond of either of the three guys' voices, but I have a feeling that's not why they were cast.
