Claudia Christian mentioned in a blog post the other day that a B5 director ("who had clearly never watched the show") had told her to play her scenes with Sheridan more "sexy and coquettish" and I had such a strong "EWNOGROSS" reaction that I had to step back and analyze why. I can handle all kinds of fic/pairings, even if I prefer to avoid them. But Sheridan/Ivanova disgusts me, and thinking about it I've come to the conclusion that it's because they're too much like siblings.
It's kind of funny, I suppose. I can handle all kinds of screwed-up pairings if I understand the kink, even if I don't share it. I can deal with non-con, power imbalance including parent/child incest, aliens... lots of stuff. And I'm on IJ substantially because I used to have a good friend who wrote and read Weasleycest, and while I wasn't into it I didn't like the idea of her ability to do so being restricted. But despite this, sibling incest remains one of my biggest squicks.
Maybe it's because I have siblings I'm close to, and the idea of people perverting that kind of relationship feels too close to home. But I have parents I'm close to, too, and I can handle parent/child type stuff. I suppose in the Sheridan/Ivanova case, there's the added factor that they're not related by blood or by legal definition, and I've got those siblings too and know how upsetting I'd find it if people ignored that and assumed that we were sexually involved. Ties in to the whole "a man and a woman can't be just friends ever" cultural assumption, which I hate because I used to be the girl who had all guy friends and wasn't into any of them, no, really, stop teasing me, Mum! *coughs* Tangent there. Anyway, I think there's another factor.
Actors are often treated as people whose job is to convey emotions, deliver lines, and embody personalities. They are, of course. But another job they do is play relationships, and they're often not as good at that. We've all seen a big romantic storyline completely fizzle because the main romance lacked chemistry. Then, too, parent-child dynamics on screen and stage often fall flat. But the most commonly disappointing relationships I'm used to seeing are sibling ones. Screen siblings, whether bickering or affectionate, tend to fail to convince. And so I guess when I see a sibling relationship I like, I really don't like seeing it taken through the "a man and a woman can't be just friends ever" cliché. So Sheridan and Ivanova, whose sibling vibe seems so clear to me, I can't bear to think of in a sexual situation.
(Claudia Christian, I may have mentioned, is brilliant at playing relationships. Yet another reason I love B5.)
