It's always been about...everything. I mean, that's why I loved it as a kid. I was (and am) the most dramatic kid on the planet and I loved the horror, comedy, and action so it was just the perfect show for me. It kind of depends on what I'm in the mood for. I feel like every episode has a little bit of drama in it, so that's a given. If I want action, I watch Graduation Day Part 1&2 (The scene with Buffy and Faith, in Buffy's dream used to make me cry as a kid. Yes. I actually cried.) or Becoming Part 1&2...and, well there are ton that I could watch for that haha
If I want comedy then I'll watching Superstar, Something Blue, The Zeppo...yeah. I can't pick just one aspect of the show! Haha...ugh. The scarier episodes (what I considered scary back then) were what caught my attention originally.
Also, the fight scenes are insanely cheesy. I still love them but they're so ridiculous haha sometimes I just crack up at how crazy they are. I do love the Buffy/Faith fight in Graduation Day Part 1...and it may be one of the cheesiest.
I love cheese.
