It's got a good cast, good pace. Some people criticize how they portray the crazy Christian woman but there are actually people like that in the world with mental health issues whether they want to admit that or not. Yes the ending was negative but when you see the world is full of these creatures that are humongous and deadly and you have nowhere to go, you feel that you'd rather die than get attacked with horrible pain by one of those. He thought the world was over so he made that choice to end it painlessly. It's a dark movie that does show how people would act. Look how they act now in real life. It was a well acted and well made story. I'm giving it a 4 Soley on the fact that I like happy endings and it's hard for me to watch the ending to this
