Agreed. We already have a show set in the zombie apocalypse. I want to see how we got from here to there, and this show so far is delivering.
Well, he did that, and his friend tried to kill him, so... maybe running out of options.
Well, yeah, that was the point. There were several deliberate shots of him shambling like the zombies do, severe fake outs to tease the zombie apocalypse to come but that isn't here yet, etc. The show played very heavily with visual foreshadowing and parallels to the upcoming apocalypse, and the shambling half-dead addict-as-protagonist reminding us of zombies was one of the more obvious ones IMO.
