I was disappointed. It was really slow, especially for the length of the episode. They could have easily got everything into a normal episode.

Minor quibbles that annoyed me - How could his mother have possibly known which random pile of bedding was her sons?
Why would they leave the only piece of evidence tying the son to shooting his dealer next to the car? How did they possibly drive past the zombie in the gully access without noticing him?

I really hope it improves, cause I enjoy the walking dead, but I'm worried now the opening episode was so pedestrian.
