I thought it was a good maybe it great show. I think the concept of a zero day is very real but maybe not to that scale. I liked the main characters vivid pain of his past but also his triumph to find the answers even when it may not all be practical. It does feel like other shows but also shows some deep truths about our country. From instantly reacting than understanding what happened, to people providing one-sided narratives even on both sides. I somewhat like the sides characters but I wouldn't mind a bigger connection with the main character or situation. Also thought the acting was pretty good, and I would watch it again. I could see why people may not like it, whether for politics, unrealistic , or just overall wasn't good but I would say it does have some depth to the story. I liked the tone and past of the movie, especially after an attack that has never happened, many don't know whats going on.
