I understand that some people are turned off by the size. But the art is the same dimensions as a modern comic, so if I'm gonna put a comic on my wall to look at, the art - to me, is no different. Same size.
I think when it comes down to it, some of Adlard's art is detailed enough to tolerate the smaller pages, and some of it isn't.
When I was looking for WD OA I specifically wanted the larger art. I also wanted something early in the series....it had to have Rick and if a zombie was in there...okay but I wanted the story to be cool.
I ultimately decided on the Zombie's in the barn story arc because I enjoyed that surprise in the book and show a lot!
