In fact, this is perhaps the only Zombie movie to make me emotional. The story is easy to understand and it doesn't take much time to set up the plot. The character development is one of the best parts of this movie along with the struggle of emotions and the thrill. It has good VFX. Not the best but certainly better than average. The movie is never particularly scary but it is a thriller and a tragedy in my opinion. The ending is one of the best movie endings I have seen in a while. The pacing is really good and you can easily re watch it a lot of times without getting bored. One of the best movies ever made in the thriller/zombie genre.
