I bought season 1 because he'd been watching Firefly and Serenity over and over. Which he still does; he re-watched Serenity just the other day. But I was tired of it, and I told him it was time to watch the show that made Whedon famous. We watched it in bed, curled up together with my Powerbook.
I am still extremely fond of season 1, the high school Scoobies, the library, the Citroen, cute curvy Buffy, geek-chick Willow, and shaggy Xander. And of course Giles in tweed, checked shirts, and striped ties, with his cuffs unbuttoned.
