You won't miss anything if you don't watch this movie. While this movie has good action sequences, the writing was beyond terrible. The movie tried to explore new ideas like zombie hierarchies and babies, but they were never expanded upon. You have a zombie heist movie with a group of characters that prepare as if they are going on a merry road trip. As the movie progresses, it gets more difficult to ignore the piling plot points and idiotic decisions of the characters. The worst part is that it takes itself seriously when they make comically bad decisions.
