It sticks to a more realistic storyline, then the alien and zombie end-of-the-world-as-we-know-it series/movies. With this series it made me want to see the next episode. Storyline is basically a virus that kills all but who are immune. Then as a normal virsus goes, it mutates and kills more. This story show a group forming of survivors and how they deal with different situation including shelter, food, and angry people with guns. They are somewhere in the UK which I think has gun control, hence not very many guns. Anyways, I don't want to give too much away, so this review is rather bland.
