Heh, I also find both Jack and Lee occasionally annoying. Jack more than Lee by a lot, actually.

Juliet/Sawyer is my favorite pair on the Island but I don't think of them as being like Kara/Sam at all. I find Sawyer tolerable when he's with Juliet, but don't really like him otherwise... and I do, in fact, like Sam. Period. Lost is a show I watch way more for plot than for characterization. Oh, and I watch for Michael Emerson being twisty and for the Ben/Island/Locke shippiness, heh. (Who knows where that's going now?!)
