Part of the problem is that people are too familiar with the movie. Its like when people go to "Grease" expecting to see a stage version of the movie and then get mad when there are different songs, etc. You just want to shake them and say "HELLO!!! The stage show actually came BEFORE the movie!!!" I don't think it would be a big success unless they staged the movie, which would be a big disappointment to avid Broadway supporters, in my opinion. Though I suppose Kevin Bacon would be a ticket draw.
