Query: Fun Book but not great.

I started it once a few years ago and set it aside but The Walking Dead on TV made me pick it up again. I enjoyed it but i do not think its great. The style is original. A bunch of seperate stories without a cohesive story line. That's what i did not care for. I know that a lot of people like the style of the book but to me, it felt incomplete. Like there was no true beginning or true end. There wee no main characters. No one to root for. It was just a bunch of small vingettes. Too many questions left. How did it start? How did it spread so fast? How did the dead manage to live under water without being crushed by the presure? It was an enjoyable book but left me feeling like there should have been more. Oh well.
