Er. Uh. Hm. Talia Winters/Susan Ivanova on B5. Not because they're both women, but Talia Winters was frankly always a rather obnoxious and annoying character, and paring her with probably the dullest human character wasn't a move I was that keen on. Well, it was short lived, hurrah.
Andrea Thompson made a good living playing obnoxious and annoying characters, she not a bad actress, she just written that way. Hate her on one of my fav shows "JAG."
The forbidden romance between Jack O'Neill and Samatha Carter, the slow build up was a bit interesting at first. But they had no where to go with it. Carter's go no where engagement to that cop was no better.
