1st the show it got you in tension the whole time. It has not a lot of talking which is great for people like me that gets bored easily when they start talking and talking (unless if it is "The Last of Us" that it is another show 5/5) adding to this, it does has a lot of unanswered questions but so far they did not wasted the viewers time in agony of how long a person is going to turn into a zombie. No matter what, they should keep it realistic and do season 3, if "Nation Z" did a bunch of episodes with unrealistic stories, this could make it too.
