There are as many answers as there are people. I have little preference -- I go with what fits in my schedule. for example: I likely won't be in the city again until November -- my two show choices will likely be The Band's Visit and Once on This Island. One just starting previews and the other just past opening.
I saw DEH off b'way, and on bway -- but only saw Waitress in Boston. If I'm not moved/exhilarated by the first time, I'm not going back at all- regardless of improvements I hear about.
If we're not having fun, then why are we doing it?
