I read the comics too. What I enjoy about the show is how they use the comic as a base, then alter it on the show.
The comic governor was a freak show. Yeah he was twisted, and a murderous rapist, but on the show he was so much more smooth and calculated. Andrea on the show was a total screw up. Lori on the show was annoying as hell. Shane on the show was WAY better than comic Shane.
Some of the stuff in the comic is portrayed more graphically and for shock value. Yet the show has also taken some of the simer arcs in the comic and made them way deeper and meaningful. The best example of that is The Grove episode.
I should receive the next volume of the comic this week, pretty pumped for that. What excites me for this season is how they will overcome the next obvious obstacle and how they will introduce some upcoming vital characters.
The Shane / Lori/ Rick and how long the relationship went on and the arc of Shanes character unfortunitely made me dislike Lori more, which withdrew from her ultimate death and what it met to me as a reader. I remember when she died I was crushed and felt what Rick was feeling. In the show, I kinda hated her.
I agree with everything else you say. I did think the show did a good job with the Carl rape scene and that was intense. I remember cheering, when Carl is saved. I think it was slightly better then the book.
I did however hated how they treated Tyreese. I remember the prison scene in the book when he goes into the gym full of walkers with a hammer comes out with them all killed. I was like that was one bad sob.
I think in the show they betrayed him way to late in the story arc and way to soft. However I love Eugenes character in the show much less annoying then in the book.
