I really enjoyed it. The Seinfeld stuff in particular was great and it was definitely better than the original Seinfeld ending. We got to see Jason Alexander run for the first (and last) time ever and I've pre-ordered my copy of 'Acting Without Acting'
Was it the last ever episode? Hard to see any more Curbs being made after this, I think it was a good place to end it. Naybe Larry has finally recovered from Sour Grapes and will try his hand at another movie.
