Michonne is going to be a very badazz character if they give her the liberty to do so.
Lori is now, by default, the most annoying, antagonistic, conniving witch left on earth. She really needs to join the undead. Hopefully she will. The actress that plays her basically sucks. It doesn't follow the comic book verbatim, but in this case I certainly hope so.
The arc of the human side of the story is how the ones left alive approach and deal with their destiny/humanity as it's forced upon them. It's interesting to see the gradual development of the characters based on the outcomes of what happens during the show, doing things the characters probably wouldn't be doing in a "normal" life, had it not been for zombies.
Maggie is kinda hot actually.

Especially when she's chunkin' zombo's.
I like T-dog and Glenn, and even Herschel. They all have something to bring to the table. Even though T-dog didn't get much in the way of story or speaking lines ever since he got in a fight with Merle on the roof.
It's definitely intense. I don't think I'd have made it past the outpost outside Atlanta way back when if I had to do all that for real!
