It's definitely worth it. The best, I think, is that some Broadway shows in previews show up on tdf before reviews-- then don't show up again if the reviews are good and business consistently increases after opening. I saw Drowsy Chaperone front mezz for $35, and it was awesome! I don't think I've ever seen it up again after opening night, though. I also went to opening for Caine Mutiny for $30 or so, which was interesting because I'd never been to an opening night. I've seen Spring Awakening, Martin Short, Light in the Piazza, Sweet Charity, Dirty Rotten Scoundrals, Brooklyn, and passed up on Little Women with it. Not all those shows were great, but the seats have always been very good for the price (sometimes orchestra for $35). I've seen a lot off-Broadway too, and there's even opera and jazz concert offerings sometimes. The recent Rockapella concert looked interesting, even though I didn't go. Do it Rockapella!

"I thought that that was just going to be a like one shot deal for me, you know, but they kept talking about it like, 'when we do the production, when we do the production', and I was like, 'yes, yes, when you do the production, cool, I will come and see it'". - John Gallagher Jr. on SA
