I'm a Buffy fan too and loved the action more than the romance too. And the humor, of course! I like how the show's very tongue-in-cheek. I started watching it as a guilty pleasure while at university, during one summer vacation. But I didn't feel that guilty because the show was SO GOOD! I finally admitted to a friend and she said, "I've been watching it too."
I have one more thing to say: UGH to Riley! Years ago, when the season with Riley originally aired, whenever we thought something sucked, my friend and I would say "BLUCAS!" (which is the actor's last name). It works as well as any good swear word, I think, especially if you yell it like Brando crying out "STELLA!" or say it quickly, with a snear and a hiss, "blookaas." Try shaking your fist while you say it. For exmaple: "Ouch, I stubbed my toe!" Shakes fist. "BLUUUUCAAAAS!"
