In Season 2, Chapter 2 "Trick or Treat, Freak," Max appears wearing the white mask of Michael Myers, startling the kids. In Season 4, when the kids need masks to hide their faces, they use Max's Michael Myers mask once again. The very premise that Hawkins, a peaceful suburban town, transforms into a space of horror where teenagers are killed inherits from the movie <Halloween>. The <Stranger Things> opening music, which utilizes synthesizers, was also heavily influenced by the <Halloween> theme composed by John Carpenter!
