Season 2 of Buffy. I forgot how awesome (and disturbing) it is.
Next time you feel like rewatching Buffy in full, please consider giving Lost Girl a go. It's exactly the same as Buffy but with adults who aren't afraid of sex.
Or you could investigate Todd and the Book of Pure Evil which is exactly the same as Buffy except it's about a stoner simpleton who is only fighting evil to impress a girl.
The same but different.

Us and Them.
