As a watcher of many movies and Dramas in this genre, story is usually secondary to the unwritten social contract break down. Usually we play nice with each other as humans but when we add death as a consequence, things we would never have done suddenly become acceptable. Survival is so hardwired into us.
The Story is actually the star of this drama, the mains not instant badasses, flawed and yet over come the flaws through the course of the episodes, Or not and accepts them.
No one is overly naive to propel the story, just everyone has their own back story and reason for who they are (kinda like real people).
The transgender plot line was done extremely well and it wasn't thrown in your face, it was folded into the story like just one more ingredient AND I LOVED IT.
Acting totally on point by this star filled cast.

It gets a 9.5 because...because I cant bring myself to give this genre a 10.
