I like mike:
Have a wonderful time! I think Rent is a great show for 20 somethings, and I think that some of those who tear the show apart forget what is like at that age.
I also think the material outshines any weak performers on the stage. Even with the weakest cast I've seen, I've never NOT been moved by Rent.
If your daughter enjoys the show in NY and enjoys the movie, I suggest trying to snag some 2009 tour tickets, too. I don't think you'll be disappointed!
So, that was the Drowsy Chaperone. Oh, I love it so much. I know it's not a perfect show...but it does what a musical is supposed to do. It takes you to another world, and it gives you a little tune to carry with you in your head for when you're feeling blue. Ya know?
