THE HOLY MOLY TARDIS.

Joss Whedon is a brilliant brilliant man. He did Buffy, Angel, Firefly (and Serenity), and Dollhouse. And Doctor Horrible's Sing-Along-Blog. Which was awesome. But I really would recommend watching Buffy and Angel if you like Joss's work. They were awesome. I went through all seven seasons of Angel in like... a month. I didn't get into it until well after both were over, so I watched them on DVD, which was much more satisfying to gorge myself upon, lol. But I really recommend them. They were good stuff. And Spike is fricken amazing. :) He comes along later in the series. :)
