Buffy- Silly and, agian, not funny. Guess I'm just not a Whedon person.
Buffy isn't always intended to be funny. It's downright dark at times. And sometimes (especially early on) it was intended to be cheesy. Season 1 was shamelessly so most of the time. "I wear the cheese. It does not wear me." Buffy was one of those shows able to evoke pretty much any style it chose to on a given day, sometimes multiple styles per episode. Not many series can get away with that. Doctor Who is the only other one I can think of offhand, and even that would have difficulty getting as dark as Buffy did occasionally.
Are you sure you haven't projected your own expectations onto the experience?
Frankly, I don't understand the hate for it. Maybe it's not your thing (or maybe you THINK it isn't your thing now but will change your mind later.....I did), but it certainly did a great deal for the genre while it was on.
Besides, it gave us Angel, one of the strongest SF/F shows of the last decade. Angel is essentially all the strong points of Buffy without the sometimes-annoying teen aspects, and a more consistent narrative style.
