I found 28 days and nights umm well the concept of it is awesome but it just didn't flesh out right. its this great story but it just ends too quick with too easy of an answer. theres no character development either, and i'm not big fan of the art.
The walking dead however is where its at. the characters struggle and deal with the problem in a realistic way. it has the feeling that no matter how important you are in the storyline, you can be killed at any moment. it doesn't feel like they will be the ones that solve this mystery of zombies but merely they're just trying to survive it. i'm picking up vl. 4 today.
