Overall, box office is down for the year. I love going to the movies, but even I don't go as much as I used to--I just put a lot of them on my Netflix queue and wait for the DVD.
"Rent" as a whole has certainly made it's money and left it's mark in theater history, I don't think anyone has anything to be sorry about. It's got a whole new generation of fans, and will for years to come--especially now that it's a film, whether you liked the movie or not.
It's Broadway--it's a limited audience no matter how much you advertise it. Look at the ratings that the Tony's get (even with Wolverine hosting).
That being said, I think "Rent" will do gangbusters on DVD. I loved the movie, I can't wait to get it myself.
Rentheads...just enjoy the movie. And don't let the snobs hit you with 'I told you so' over anything.
