In suspense movies like this, the interest often stays until the very end. The viewer keeps wanting to watch the movie and understand the story properly.

I have not watched this movie yet but I have seen a similar movie where almost everyone in the world dies because of a disease and only two people survive. The story shows how those two people try to survive in an empty and abandoned world. It was a really good and powerful story. I have forgotten the name of that movie, though.

The movie you are talking about also sounds very interesting. When I get some free time I will definitely watch at least its trailer. 🙂
