I'm puzzled that some people recommend that Buffy virgins should skip S1 and start with S2. It's not as if S2 doesn't have a good selection of clunkers and, in order to get episodes as good as "Innocence" and "Passion", you need to develop the characters and plotlines; you need to have earned the right to break our hearts.
If you don't get Buffy after viewing "Welcome to the Hellmouth" and "The Harvest", I'm surprised if you get Buffy at all.
"Nightmares" is great. That is all.
