“Dollhouse” returns tonight — Summer Glau alert — with two episodes (8 p.m., Fox) as it ends its bumpy two-year run. To mark the occasion, Maureen Ryan, the excellent TV writer for the Chicago Tribune, interviewed Joss Whedon, the series creator. Among the topics discussed: the frustration dealing with Fox’s fears over the show’s exploration of sexuality and intimacy.

“This is the thing that caught me off guard. First of all, network television has taken great treads backwards in terms of dealing with sexuality or the body or anything. I mean, now on cable everybody is prancing about naked and whatnot. On the networks, it’s gotten different since I was last making TV. Fox sort of has that reputation for ’sexy’ or ‘edgy’ or blah blah blah, but they don’t actually want that and it frustrates me,” he continued. “It’s the classic American double standard: torture — great. Sex — oh, that’s so bad!”
