I am in a similar boat! There are very, very few characters I really dislike - and I tend to love the ones many people hate or don't care about. Fandom can feel weird.

Sometimes I want to slap characters upside the head, but that just means they're human (or, um, sapient, anyway). I usually find them sympathetic and interesting, in various degrees.

I understand thinking a character just wasn't well-written and dragged down the show, but taking that personally, downright loathing a fictional being...tends to baffle me.

I hated Owen on Torchwood, but that was more about the way his actions were handled and what that represented.
