The Monsters Are Due on Maple Street Theme: Lies cause chaos
In "The Monsters Are DUE on Maple Street" by Rod Serling, one of the main themes is that Lies cause chaos. I think this is the theme because everyone was blaming everyone and going crazy because Tommy claimed their was an alien in the town. Everyone started blaming everyone because of everything happening and everyone got super stressed out and annoyed. Causing the lie to spread. Everyone started freaking out ad getting scared and worried that someone else was the monster and they didn't figure out who it was. No one ever figured out who it was and the real "figures" were just testing them as everything went crazy.
Evidence 1: In this scene everyone blames Les because his car starts right after Tommy said that someone in the town was a alien.
Evidence 2: In this scene Charlie shot Peter in fear that someone is an alien pretending to be human.
Evidence 3: In this scene : everything started acting weird lights flashing and lawnmowers starting causing everyone to blame each other for the situation.
