The good: -The intro to the second segment. Very different style.
-The backgrounds for the Peanuts parody. They looked airbrushed, very cool.
-While I wasn't a huge fan of the second skit, at least it had an original premise. And the joke about John Wayne's films stitched together to make a sentence was pretty good.
The bad: -Everything else. Man, where to begin.
What was the point of killing Homer in the intro? It made no sense. If the machine was rigged to give McCain votes, logic would stand that it would let Homer press it as many times as he wanted, not only allow six and then suck him up. Just another excuse to kill a character for no reason, I guess.
The Transformers conclusion, with the robots realizing that they can work together to enslave the human race, has been done before on this show. And why was a Transformers skit part of a Halloween special? That's as big of a stretch as Disaster Movie's material. Oh yeah, Homer's "I got Seinfeld season 7 on DVD" comment wasn't funny, so why include it?
The dead celebrities skit had too much gore for my liking. While the Treehouse of Horror specials were never squeaky clean, I can't say they ever showed someone being ground alive while screaming. Even "Nightmare Cafeteria" never actually showed anyone being processed into food, and it was creepier for it. And Lincoln acting gay... why?
They barely took advantage of Peanuts for the parody aside from a rather bland "trombone noises for dialog" joke, the low budget dancing (which was only on-screen for about five seconds!), and a couple of the characters fitting the archetypes.
It WAS better than last year's, but that's not saying much. I still didn't laugh much at all, nor did the special have a spooky atmosphere. Remember THOH IV and V? Why can't modern specials be like that?
