Really loved BILLY ELLIOT the musical beyond all sense of reason. I disagree with the ending, but was still very moved by the whole thing.
SPOILER
I truly think that his inability to control his temper in hitting that other small kid (during the friggin' audition process for Gosh sakes) should have required that he not be admitted. But that's fiction for you. A peculiar plot point, though, his hitting that little kid, given the ending of the show.
