Haunting of a different kind comes in the excellent "Conversations with Dead People" (one of the show's most terrifying episodes ever), in which a mysterious song is making Spike kill again in spite of his soul and his chip. Giles turns up in "Bring on the Night" and Buffy has to fight one of the deadliest vampires of her career in "Showtime". In "Potential" Dawn faces a fundamental reassessment of her purpose in life.

Buffy was always a show about female empowerment, but it was also a show about how ordinary people can decide to make a difference alongside people who are special. And it was also a show about people making up for past errors and crimes. So, for example, we have the excellent episodes "Storyteller", in which the former geek/supervillain Andrew sorts out his redemption while making a video diary about life with Buffy; and "Lies My Parents Told Me," in which we find out why a particular folk song sends Spike crazy. Redemption abounds as Faith returns to Sunnydale and the friends she once betrayed, and Willow finds herself turning into the man she flayed. Above all, this was always Buffy's show: Sarah Michelle Gellar does extraordinary work here both as Buffy and as her ultimate shadow, the First Evil, who takes her face to mock her. This is a fine ending to one of television's most remarkable shows. --Roz Kaveney
