I second that. There are some characters that become grating after a while.
Yeah, there's a few I really can't stand, still!
But as far as liking someone you hated - Wesley. I am not a fan of slapstick, and I really disliked him in Buffy. I don't like characters who seem paper thin and brought in for comedy. In fact, he was why I had to be strong armed into watching Angel. Now, I love him - he fascinates me. His journey is so much about finding and getting beyond all the restrictions and all the pain. But in every part of his journey he remains moral - he does what he knows has to be done. He may be wrong but he does what he knows is right.
Angel - I wasn't an Angel fan from the start. I liked him a bit - liked him more when he became Angelus (except that he hurt Spike's feelings
🙂) By season 3 I was done with Bangel and Angel. Then I watched him on his own show, and he too seemed to develop so much depth and complexity. I didn't approve but I flat out loved it when he locked the lawyers up with Darla and Dru.
I like Dawn and Anya but as the show moved on they did so little with two really great possibilities. A 1,000 year old demon used as a perpetual orgasm joke, and an ageless ball of energy with apparently only one use.
Dru annoyed the crap out of me - now I love her.
I still don't like Xander all that much but I do appreciate parts of him more. I always liked Cordelia but I really grew to love her on Angel.
Faith - omg, couldn't stand her. I hate the whole rebellious from abuse trope. Then I watched Angel, and she is now one of my absolute favorites.
