It took me a while to warm to it actually. I am looking forward to the second season. It did lack a little complexity and I was kinda disappointed. Matt Berry voicing Snip was hilarious. It certainly had a cartoon like element to it, unlike say, The Last of Us.
Currently watching the second season of American Rust which I think is brilliant. Took me two episodes to click with it but it's very well done.
I guess most of the complexity was implied by the whole game lore. I ca see it has potential, and once a number of season have been made, I can see it becoming a really good show.
As for the other titles you mentioned, I'm not familiar with either, but I'm guessing they are similarly post-apocalyptic ones.
