Ironically, my main area of concern is whether the single episode plots/ideas they come up with can successfully blend into ongoing plotlines. I guess I'm almost hoping for a regular number of set personalities to keep cropping back up.
Oh, and the computer guy/wiping geek : too creepy for comic relief, too goofy looking for bad guy status. (Too much Andrew, too little Xander?) And that I suspect is by design. No all-good guys, no all-bad guys.
