The Mousetrap has been running in London for, I think, 60 years. The British love their murder mysteries. The only reason I can't see it playing Broadway is because every community theater, high school, college, church and senior citizen's club does it. But it only has eight characters and one set, so it seems like it could be produced fairly cheaply.
I didn't like that last revival of Our Town. Jane Curtin, in an attempt to play hardy New Englander, came across as mean and spiteful. And I never really felt that Ben Fox made the transition from awkward teen into grown man.
But like Gypsy, Our Town is part of the American canon and should be produced professionally at least once every decade.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
