Honestly, I don't dislike anybody, at the moment.
In present-day, I don't mind Ben, he's a cutie. I feel bad for him mostly! The poor guy is getting the cold shoulder for no reason that he's aware of! Yvette is just too funny. I feel bad for Liz as well and hopefully Bea and her can patch things up. John has grown on me, too, mainly because if Liz feels he's worthy to date, he must be a good guy.
And in the past, we all love Alan and Nathan. I don't dislike Hamilton, he made me laugh despite he was a jerk sometimes! I think all the characters are developing, which is a good thing.
--Oh wait, I don't like Howe. Well, I do but I don't. He's a great bad guy, but that's just the thing. He's a *bad* guy!
