I've just watched the clips and it only served to make me more excited for the film.
I think making an instant decision that something is bad or doesn't work based on a minute long Youtube clip is a bit hasty. In the cinema in the dark with a huge screen and wrap around sound, I'd like to bet that everything will be as people who've actually seen it suggest.
Anyone expecting the same experience as the show is bound to be disappointed. For that we've got the live show, the 10th anniversary DVD and the 25th anniversary DVD. This HAS to be different otherwise what was the point in making it?
A good example for me, The Producers musical movie was awful even though the show was superb - because all they really did was point a camera at the stage show. It didn't work.
This is a movie first and foremost, and I'm sure in context we'll all be thrilled *buys popcorn*.
