If you were ever a Buffy fan, you should at least check out the Spike episode. It's the first episode of this season, so there's not a lot of background or anything. He basically plays his character like a gay version of Spike. I think that's really all James Marsters can do. He's also dressed ridiculously. He has like cowboy pants and boots on, the shirt and jacket of a 18th-19th century French soldier, two modern/scifi-y pistols, and a katana.
