I have to ask. What's the point of this show? Girl discovers that she is human. Is that it? Because that sounds kind of boring compared to Whedon's previous shows.
I laughed at the title/concept of "Buffy the Vampire Slayer," too. It's now my all-time favorite show. I thought Firefly sounded kind of ho-hum, and ended up finding it brilliant. Whedon is a master of taking a concept that sounds either ok or even not all that great and turning it into something phenomenal. I've got faith in the guy (and no, that's not blind faith--if he does something that's not all that great, I'll point it out).
It's never a good sign when production shuts down. That being said, it's a mid-season show and they've got some time to work out the kinks.
