I really enjoyed it, I really wish they hadn't killed Omid,Christa's baby, and probably Christa right of the bat. It honestly felt kind of lazy. I also didn't like that you get no hint as to what happens to the 400 days survivors, besides Roman's corpse. Another thing that bugged me is that you learn NOTHING about the overarching plot for season 2 in episode 1. Who the fuck is Carver? Also, I didn't like the pregnant woman (Rebecca?) as a character since she seemed to exist just because every group in a zombie apocalypse needs a antagonistic asshole.
But yeah, besides those complaints I liked it even if some of the scenes were heavy handed in their attempts to make you sad and your choices didn't matter too much.
Choices:
Became BFFs with Sarah (No need to be a dick unreasonably.)
Helped Christa (She is your only surviving friend, why wouldn't you help here.)
Mercy killed the dog (I don't understand why someone would leave it to suffer. It doesn't understand concepts like betrayal and empathy. It had food aggression and attacked someone who either took it's food or never gave it any.)
Accepted Nick's apology (I understood)
Gave the dying man water (I wanted to know who attacked the them and what happened to Christa.)
Saved Pete (Pete had my back when I was surrounded by zombies, when everyone but him and Luke wanted to shoot me, and when everybody though it was wrong of me to steal. It was a very easy choice for me. He also looked like he needed my help more anyways, and in the end Nick survived, so all is well. Loyalty over personal safety in my opinion.)
