Bear in mind I'm not a comics fanboy or a tv show apologist. I'm middle ground. I read the comic only once after season one, and it was very good. Also I enjoy the show and I have seen every episode once, so I have not overly analyzed or digested the tv plot or characters.
I know that the TV show's portrayal of the governor has been discussed to the point of ad-nauseum, and has generated many flame wars. So in the spoiler I have linked an image to the reasons why I feel the television character has not reached his full potential.
