Will DOLLHOUSE be a stinker?

Word on the Internet is that Joss Whedon's new sci-fi TV series Dollhouse, set to debut on Fox next month, has "bad vibes" written all over it. But it looked good to me when I saw trailers at the Whedon/cast panel last July at Comic-Con. Besides, it stars Eliza Dushku, so how bad could it possibly be?
