There are not many shows I hold in as high regard as Buffy. I watched a few old episodes recently for the first time in years, and they still hold up so well. It just fused its component elements together so well: the writing, the characters, the acting, the action scenes, the comedy, the drama, the experimentation. Some shows today bang out a really strong season, maybe even two or three. But few seem to stay as intriguing as Buffy did for me.
Even though I didn't find most of the seasonal arcs or Big Bads after season 3 as compelling (how do you top Mayor Wilkens and the Buffy/Faith arc?), I grew to love the characters so much, and their actors did such a great job inhabiting their skins, I could forgive most other shortcomings. And the later seasons still had so many great stand-out episodes.
I'm not shocked that the Kuzuis want to reboot Buffy and try and capitalize on all the vampire hype (although they should really have done that a couple years ago before vampires got too played out). But I'm not expecting much of anything from it, considering what they did with the property back in 1993.
