I'm surprised so many people loved the episode and are specifically praising the writing. I was so bothered by the fact that scenes played out like:
#1. Viewers are introduced to Bill. The one thing we learn about him is he is a shrewd survivalist who is overly careful, distrusting of others, and willing to sacrifice human contact to ensure survival.
#2. Random guy falls in trap. Invites him inside and have sex within 10 actual minutes.
#3. That random guy you fell in love with IMMEDIATELY: Time has passed and now you have reason to trust him. He invites friends over for dinner and vouches for them, Bill doesn't take his hand off his gun for the entire dinner, because obviously this guy is a shrewd survivalist who is overly careful.
So we are told one thing about a character, and he is immediately betraying everything we know about him. I spent so much time waiting for this guys' idiotic actions that betray everything we know he stands for to come back and bite him in the ass like the dumb character in a horror movie, but it doesn't even get addressed.
I'm no writer, but that seems like bad writing to me. There were lots of other little things that had me rolling my eyes, but this was the big one that did a bad job of setting up the whole episode. The writers needed the romance to ignite quickly? Ok, make the purpose of scene #1 to establish that Bill is yearning for human contact. Make him go out on little missions trying to find someone to interact with or something. Make that who he is.
Their whole story felt rushed, which shouldn't happen. An hour should have been enough to tell that story in a well-paced manner. If not, extend it to other episodes. In general, I don't like serious "zombie" shows/movies because there's too much I can't just ignore. I wanted to give this one a shot because I enjoyed the games, but so far it's not drawing me in and doubting I continue after season 1, if I make it that far.
