One of the best episodes of Season 10
18 November 2007 | by (Australia) – See all my reviews

This is not only one of the best episodes of Season 10, but one of the greatest Treehouse of Horror's of all time. It delivers some great jokes, some that are mostly absent from the rest of this season.

This episode is just a breath of fresh air after the last two disappointing efforts (VII, VIII), which were actually quite bad.

But above all else, it's just a clever episode. Quite consistently good. The first two segments were the best, but the third one was still watchable.

If all Season 10 episodes were as good as this, it might just be better than Season 9. If you're a fan of the prime, classic seasons (how couldn't you be?) then I'm quite sure you'll enjoy this episode, if only on a few levels.
