The theme of the teleplay "Monsters are due on Maple Street" by Rod Sterling, is fear is our greatest enemy. This is the theme of the story, because in a scene where Charlie becomes fearful and anxious he feels as is everyone is a suspect including Steve. This causes him to want to blame Steve and therefore break the trust and bond they once had with each other. In another scene where a dark figure can be scene coming towards the group of neighbors. Charlie once again becomes fearful and anxious so he takes a gun and without thinking twice, he shoots the figure which he believed was an alien. This causes the neighbors to swarm the body which turned out to be Pete Van Horn, one of their neighbors. The fear that swarmed the air caused Charlie to not think twice about his actions and murder a man which just goes to further prove how much of an enemy fear is to humanity. In one of the last scenes, where everyone begins to panic with fear about who the alien might be, all of the neighbors begin to blame anyone they can because they so badly want to find a solution to their conflict. This shows how fear affected all of the neighbors very negatively, and caused them to all stab each other's backs and brutally blame each other for an action they had no involvement in, breaking any bonds, friendships, or ounces of respect they may have once had for each other. Overall, in this teleplay fear seems to bring out the worst in all these characters, and it just goes to show how cautious we must be about how fear affects us and the decisions we make.
