You're so right about the critical threshold. Somehow this bothers me a lot more with a pairing like Kara/Lee than Clex. I am reasonably tolerant of absurd Clex fics, because I'll read Clex for humour and simple eroticism, not necessarily plot. But that's not what I want from Kara/Lee at all. I see *why* it's happened, but it will still annoy me. They are so well-written and understated within the show, that much fanfic will be a letdown.
