MeggilyWeggily,
I completely disagree with your thoughts that most of the fanbase is way to young to understand what a revival is. Actually, most of the original "Rentheads" (you know, the ones that slept on the street before there was a lottery) are now in their 30's and 40's at this point. Far old enough to understand a revival.
Though if this is a revival, a revamp, or a remounting seems to be in question. Everywhere I read about this production, someone is saying something different.
Frankly, I think there was alot of different ideas about what this was (other than a way to bring Rent back to New York and make some money), and one way of artistic thinking was never fully chosen.
I don't think that comparing the general feelings garnered from the original production and this staging is particularly wrong.
You walk away from most shows with a feeling, and that feeling is what makes something enduring, meaningful, and lasting. The revival of Normal Heart still left many with an urgency and feeling of grief even though times have changed. In the latest La Cage revival, you still walked away with a sense of hope and family even if the thought of two men as fathers wasn't as groundbreaking as it once was.
If Greif doesn't acheive the same type of emotions or truth that were embodied in the original production (which in my opinion are far more general than time specific : enduring love, friendship, acceptance, passion for an art etc), then that could be saying something about the production - not necessarily the fanbase.
I guess what I'm trying to say is that one can not like the "revived" "revamped" "returned" production for reasons other than they don't want change.
For example, I actually LOVE the changes to Contact and Over the Moon. I even love the new takes on the characters. But I feel like other directorial and artistic decisions distract the audience from the story being told.
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?
