My wife has never been a genre fan, but yes, you can make inroads! ;-) I started "converting" her with Buffy the Vampire Slayer, beginning with Season 3 when it first aired -- the best season, IMO -- and it grabbed her interest immediately. I got her quickly up to speed with VHS copies of Seasons 1 and 2. Babylon 5 was a hit with her, too, but not much else since then. She never got into Star Wars or Star Trek, aside from the huge crush she got on Chris Pine after seeing the Trek movie. Alas, she doesn't share my love of Doctor Who. However, she did kind of watch the last Who Christmas special with me, even though she claimed she was doing "other things" on her iPad. I know because she laughed at a couple of the Matt Smith lines. ;-)
