The only thing that bothers me is how great broadway performers get devalued in a way when bigger names take over for them in the movie.
Ex: Rosario takes over for Daphne and suddenly all the movie fans think Daphne sucks just because she wasn't in the film. They don't realize that Jonathan Larson picked her for a reason and that Rosario probably couldn't carry a tune in live theatre because her voice doesn't have the power, it's just dubbed.
Otherwise, I think movie musicals are fun and they should in no way stop being made.
"It means nothing to come and sit in a theater night after night and immerse yourself in fantasy, only then to walk out the door and be unchanged in reality. This show will live on in our hearts. But where it truly must survive is in our actions, our compassion and our generousity of spirit towards one another." - Adam Pascal on the closing of RENT
