Regarding the Governor; well, he is English; I think that's about as crazy as they get short of going full-on Monty Python.
The Governor in the comics did some pretty fucked up things to Michonne...things you would want to do to her... whilst she was tied up. Think what he did to Maggie (in the show) only 100x worse. This is the reason she goes to kill him. (She takes, his eye, his arm, and his dick and leaves him for dead)
In the show he really never did anything to Michonne. We know he sends Merle to kill her, but you would think her anger would be construed towards Merle. I just think they needed to show him a lot more off his rocker than he is in the show....he is pretty fucked up in the comics.
I know they aren't trying to be the same as the comics...but I felt the fact that Michonne ran off specifically to wait for him and kill him was a little out of place (had I not known what I did from the comics).
