Really, I liked the whole thing, from beginning to end. I loved the Tetris bit. And it had some real heart to it too. A lot of people have been shitting on it in this newsgroup, and I can't really understand why. Overall, with the exception of a couple of duds, this season has been very entertaining, and I'm glad that Al Jean is going to stay on as executive producer. The show has been consistently showing improvement from the later Scully episodes (I say 'later' because Scully's first season or two producing the show was actually pretty good for the most part; it wasn't until the 1998-99 season that things really started to decline).
