I felt much like "Zombieland" did "The Walking Dead" chooses to focus on characters who the audience can feel an emotional attachment to and follow through the series and really the zombies are secondary.
I loved Zombieland
. I agree that one of the main reasons it did so well was that it was so funny and we actually cared about the main characters. Hopefully this is will become like that too. The father and son relationship already looks promising. Now we just need some kickass female characters!
