It's fucking great! It's supposed to be chopped into little episodes, but it has everything you'd want in a movie: laughter, tears, dancing, Scott Walker, and, of course, a deliciously predictable ending. Not to mention 857 past episode references that made me go running into Wikipedia as soon as the movie was over!
I don't see how it can get any better than this. They might as well pull the plug on the rest of the movies and kill themselves.
