Actually my point feeds into your point. I don't like UST that is drawn out too long (which is why Kara/Lee lost me and Logan/Veronica came close, but recovered). I can buy John/Aeryn, who have sex in the middle of S1 and slowly grow closer and confess their love at the end of S2 (but even before that, they are good friends) because it's written believably and they have valid internal reasons for why relationships with anyone are a bit compicated for them. But when TPTB do the soapy seesaw, I just mentally check out of there.
