I didn't really care for this episode. But I've only seen it once, and I got Season 5 from my library, so I'm going to watch it again. I have a feeling that I must have been tired the night I watched it, or thinking of something else, since everyone seems to love it.
BTW, my favorite season finale is still Season 6, with Season 7 a close second. As great as Buffy is, I think the stuff in the middle and middle-end is better than the finales.
From my tone, it might seem like I'm a "hater." I'm not. I love Buffy, and I'd rather watch the worst Buffy Episode (the Beer episode) than just about anything else! 🙂
