As someone who loves British theatre, I'm excited when acclaimed productions come across the pond. As much as I'd like to take several trips to London every year to catch all the great shows, not everyone can do that (I took a trip in May, which was my first time going in over 2 years - and that's probably more than most people are able to do!)"
I agree with this, but there is a part of me which would like to see a bit of separation - no-one wants both the West End and Broadway to be identical. However, I think the concerns over diminishing identities are primarily based on musicals - I think that things are a little different with plays like Betrayal and Present Laughter, as they are only on for a limited period
P.S I don't want to bring environmentalism into this discussion too much, but we need to find ways to bridge the transatlantic divide without flying back and forth.....
