The problems that the show encountered weren’t standalone versus mythology. Basically the show didn’t really get off the ground because the network pretty much wanted to back away from the concept five minutes after they bought it and then ultimately, the show itself is also kind of odd and difficult to market. I actually think they did a good job, but it’s just not a slam-dunk concept. It wasn’t like our numbers were huge and plummeted. They were tiny and still somehow managed to plummet. We alienated both our viewers. - Joss Whedon on Dollhouse.
I could write a lot just about the paragraph above and not say it nearly as well as he said it. Joss actually had a bit more to say and the stuff about FOX backing away from the concept (due to the sexual/exploitation/fantasy) elements were particularly interesting. As ever, Whedon handled himself with grace and good humor. I recommend reading Mo Ryan's feature and the full interview with Whedon.
Dollhouse returns tonight with two episodes at 8pm. It will also air two episodes from 8p-10p on December 11 and December 18, before taking a break and then airing its final three episodes on January 8, January 15, and January 22.
