I saw the sneak preview, and yes, they did cut the best part, but they also do a bit better visual humor in the movie that you couldn't pull off on stage. I had a number of trepidations going into the film as well, but I'm not disappointed I saw it. Is it the show? No. Is it a decent adaptation? I think so, though obviously YMMV. And if anything, I feel the second act is much better in the film (I've never been a fan of the whole By the Sea, Not While I'm Around, Parlor Songs interlude feeling that it drags down the second act, but the movie actually makes it quite enjoyable.)
