I really like seeing that guy getting what was coming to him. He had to go.

I have not watched the whole series, as I only started watching from the point where the group leaves the city (via the roof top) to the farm.

From reading the thread I learned that this show is heavily based from a comic. So far I have enjoyed the show, but I wonder if going back and watching the first season is worthwhile, or should I just keep on watching as there is nothing that is important from previous shows?

Anyhow, I am curious to read people's advise about the best way to approach the show.
