Call me traditional... but I read Lois & Clark fanfic to see the relationship between Lois & Clark :p I make a few exceptions, like the Home series and Lonely is the Man. And I've kinda-sorta-sometimes been reading the Butterfly Legacy, because Lynn's a terrific writer, but the idea of Clark and Gillian just seems fundamentally wrong.
I originally fell in love with this show on the basis of how perfect Lois & Clark were for each other, balancing out each others' weak spots, etc. In fact, I didn't get obsessed with the show until near the end of S2, when it seemed possible that L&C would actually get together. If they'd reset everything for S3, I'd have been outta there. So... that's what I like to stick with in fanfic.
