I always thought that Buffy was overrated, and was like.. The OC or Degrassi (IMO lame whiney teen crud, no offense), only with vampires.
But after hearing a few songs from the musical episode (Once More With Feeling), I decided to check it out. The musical episode was the first ep I ever saw and I fell in love with it. I started watching the rest of the series from the beginning, online.
I am now watched season 4 on DVD, and I am an obsessive fan. This show is hawt (hot).

What do you guys think of it, and/or when did you first get into it?? :D
