Adelle DeWitt: We can offer you a clean slate.
Echo: Did you ever try to clean an actual slate? You always see what was on it before.
--"Ghost," Dollhouse 1.1
Having now watched the series premier for a 2nd time, I find the most striking thing about it the relative lack of Whedonian signatures. Perhaps Heather Havrilesky is right in suspecting that FOX is scrubbing Whedon's series of all his usual cult-engendering eccentricity.
But the slate cannot be wiped entirely clean. "You can always see what was on it before," as Dushku/Echo insists in the opening scene: the most Whedonian line in the entire script and a meta-commentary on Whedon's pact with the devil in making this show.
