I think people are so put off from the rest of the show that they don't care how good the ending ballet is. Yes it may be the greatest part of the show, but it doesn't help weigh out all the negative aspects. The ballet at the end just reminds me of Sylvia's death in finding neverland. It's trying to evoke the audience into tearing up which is what we weren't doing the previous two and a half hours.
