Slasher movies left an unforgettable mark on cinema by showing that horror's best chance at success is to embrace the idea that less is more. The Texas Chain Saw Massacre was one to use this idea as it captured the attention of audiences without relying on overt gore to get the point across. Meanwhile, Friday the 13th, while violent, wasn't about the next great kill but more so about the mystery unraveling about whom the killer really is. Still, nothing matched the terrifying simplicity of John Carpenter's Halloween and its killer Michael Myers.
