The theme of monsters due on Maple street is don't jump to conclusions, someone could get hurt. I think that that's the theme because they all turn on each other and Pete got killed. In the first scene you can see how they are all in a mob and turning on each other blaming them for everything turning off. In the the second scene is when there was a dark figure is walking toward them and Don pulls out a shotgun and Steve took it from him and then Charlie took it from him and shot the figure, and turns out it was Pete Van Horn. And in the third scene is when Charlie blamed Tommy for everything shutting off since he was the only one who knew what was going to happen, and people started blaming Tommy.
