Show is very well done. Itโs a story of people dealing with a theoretical alien invasion. Itโs not a war of the world or falling skies type of show. There is not action around every corner. If you are expecting a war movie against aliens this is not it. Itโs more like a Silo, From, or Foundation type of show. There are elements of action here and there but itโs about the story and the journey.
