Thanks! That's awesome. Yeah, you really do have to know the characters, I think. But if you get the chance to watch the show on DVD, I recommend it. Lots of fun, and funnier than I remembered. I started watching it again (I'd caught a few in the 2nd and 3rd seasons because of a roommate with a Buffy addiction) because I realized it was written by Josh Whedon. Well, I already knew it, but after watching Firefly and Serenity, I realized just how funny he is and wanted to give Buffy another try.
Also, now I'm going every other disc with Angel and Buffy because I'm into the 4th season, and there's crossover between shows. I think I like Angel even more than Buffy, which is what most fans of the show when it was on used to tell me. I used to catch Angel from time to time last year when we had cable, but didn't understand a lot of what was going on with the continuity, so I wasn't as interested, but now that I know why Cordelia was on the show, it makes so much more sense.
