I am not a teen, but I do happen to love Wicked and Rent. However, I think many of you are missing a crucial point. Obviously, something about these two musicals speak to kids of this age. I'm not saying they speak ONLY to teens; I feel like many of the themes in this musical are universal . Both of the shows have stories focusing on people that are different from those around them or different than what people consider "normal." They both focus on the importance of good friends and unconditional love. They also focus on the consequence of actions and choices in one's life. I am assuming that the majority of these teen fans are female. Both shows have strong, young, unique female characters.
When I find something that moves me or that I relate, I know I love to experience that feeling over and over again. Usually, this DOES expand into an appreciation for theatre in general. The teens might see another show to follow a favorite star and find something else they love.
There does come a point when it will get old. It won't mean as much, or they will find something else they relate to more. However, there will always be another group of teeny boppers discovering these shows.
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?
