I don't see the big deal with this GREASE "thing."
It's not like they're mounting a revival of SUNDAY IN THE PARK WITH GEORGE via a reality show. Then people would say "Well, do it with GREASE or something..."
It's SO HARMLESS. It's a TV show. I, for one, plan to watch it. What's the worst that can happen? People who aren't inclined to go see a Broadway show will buy tickets for GREASE?
It's money for Broadway, it's publicity for Broadway, it's money for actors, it's a job for Kathleen Marshall. WHO. CARES.
