Interesting. Not earth-shatteringly brilliant, but an interesting concept. Missing the trademark Whedon SnappyDialogueTM for the most part, but a perfectly good opener to the series.
Eliza Dushku is pretty good, the scientist geek guy slightly irritating already and I'm slightly lost as to what the 'dolls' think they're doing all day between missions.
Will keep watching, see how it pans out. Until Fox cancels it, obviously.
