I actually think Joss was joking in that quote. I have to admit that think one of the big issues with Dollhouse is that the season was started with those godawful standalones which made it seem as if it was about making Eliza dress up in outfits and service various guys. I have heard from very good sources that JW was forced to start with the standalones by the studio, and that he was heartbroken and furious about it and that if he didn't have 100s of jobs depending on him, he would have walked away. "His" series is about all the issues of identity which started showing up midway through the season. I liked what I saw of his series, even though the season as a whole did that central idea a huge disservice.
I don't doubt that for a second, I'm glad of it for the sake of his art or message or whatever, but...I don't care. I'm not watching 6 hours of a show to make myself like it.
And still...I'm wondering, what happened to Tim's preacher man series.
