"Giles, unto every generation is born one who must run the annual talentless show. You cannot escape your destiny."
The main plot of the episode involving the dummy is uneven in places, because the dummy isn't nearly as funny or creepy as he's meant to be. Also, the fact that it takes Buffy so long to figure out that the dummy is alive (and it takes the others so long to believe her) makes little sense. Their suspect is consistently talking to it as though it were alive. It's not that difficult. But like "Witch," this episode does a great job of tricking the viewer into thinking he or she has it figured out and then revealing the surprising truth. The dummy actually ends up being quite the tragic hero, and his death is quite sad.
So in the end, it's a pretty decent episode, even if it does rely on a bit of an idiot plot.
