Oh dear. I'm getting tired of these least favourite questions because they are so negative and as Andy pointed out the answer usually involves S7 and/or Kennedy.
Well, of course, I didn't like Kennedy and Willow because of Tara and because she was pushy but I kind of liked her in "The Killer in Me" so I'm not choosing them. I didn't like the way Buffy and Riley's relationship ended but I liked their awkward romancing so it's not them (though I suppose him being a TA and her being a student was a bit iffy). Angel and Buffy were crucial to S2 so it couldn't be least favourite. Stalker Spike should have been appalling but he was so pathetic and she kept hitting him so that made it - a bit annoying - but still not least favourite.
I think it has to be Buffy and Parker. The boy screamed creep as soon as he turned up. Come to think of it so did Owen and Scott.
I think Wesley and Cordelia would vote for themselves.

There are a few I wasn't keen on:
-Spike and the girls half his age (Harmony, Buffy).
-Giles and Joyce, if that qualifies as a romance. They were lovely people, but I felt icky about that pair getting involved. C'mon guys, date outside the circle.
-Xander and Anya. Who cares?
-Xander and Cordelia. A match like that would never occur in nature.
-Willow and Kennedy. Willow settled.
If I had to choose the least fave, I think Xander and Cordelia. Just a mismatch from the git-go. That was always going to end badly.
I never thought of Spike and Harmony or Giles and Joyce as romances and so never considered them.
Come to think of it, Xander and anybody is always a bit wrong: Miss French, Impata, Cordy, Faith!, Anya, Lissa, Renee and Dawn...
Sometimes the easy answer is the right now. Willow and Kennedy. No doubt.
I like the negative questions. As long as it's not all negative, it's fine. And even the negative ones give you a chance to talk about what was wrong with X person or situation as compared to all the good ones.
