Sorry to intrude, but this immediately sparked something I read a while back precisely about two of the shows you mentioned. There's one episode of Sarah Connor Chronicles (second season I think), where Sarah gets shot. I remember that episode's depiction of violence and pain being juxtaposed in someone's meta with the depiction of violence in the second episode of Dollhouse (where she's running away and gets hit by an arrow) and it's erotically charged depiction of violence and pain. There's also the second ep, I think of the second season which gets into skeevy gender issues, when Echo is given milk inducing (?????? I know!) hormones so she can pretend to be a baby's mom. Heh, I'd juxtapose that to Weeds, showing one mom trying to get the money from her daughters modeling contract (I'm horrible with episodes, but Weeds as a whole is awesome in taking apart notions of motherhood as natural and automatic).

BSG is also another good show to mine for discussions of gender, particularly season 1 (I forget the specific episode), where Roslin (president) and Adama (military commander) clash. Or perhaps the ep, where Starbuck is sent to torture a cylon. Sorry to be so useless about episodes. Hope this helps at least a little.
