Not a great episode by any means, but certinly not as bad as some make it out to be (and not the worst episode as indicated by the voting. "I Robot, You Jane" was x10 as bad. There are some truely funny moments and the story-arc elements involving Willow and Oz were done well enough. Like I said, not the worst episode in the show's history.
For a show that can survive 20 minutes without dialogue, it doesn't seem to cope well with having bad guys that only grunt. Lame jokes and character inconsistencies abound.
Okay, now this one is very underated. It's hilarious! It's soo brainless that when I watch it I feel very smart. but that was the point! also Oz begins his obsession with Veruca. but man this episode is fun to watch. how brainless it may be.
'Xander: And was there a lesson in all this, huh? What did we learn about beer?
Xander: Good. Just as long as that's clear.'
