Well, here we go again. A show is in previews, people express their opinion of it, and other people attack those people as being either shills (if they like it) or negative (if they didn't.) A couple of points:
It's not really necessary to write "hey, give it a chance, it's in previews, it's going to get better". Everyone here realizes that.
Reading a negative/positive opinion here affects me no more or less than it does when a friend calls me on the phone and says, "Hey I hated/loved Bye Bye Birdie". I expect all of you are the same.
I think anyone here has the ability to read dozens of negative posts here, and then go on to enjoy the production when they see it for themselves.
I enjoy reading all opinions here, good and bad, and I don't think anyone should be discouraged from expressing their true feelings, whatever they are.
A truly wonderful show can't be hurt by anything anyone writes here.
Behind the fake tinsel of Broadway is real tinsel.
