YMMV / 10 to Midnight

• Complete Monster: Warren Stacy is a handsome young Serial Killer with an intense hatred for women. He murders Betty, a co-worker he had gone out with once in the past, along with her boyfriend, by stabbing them both to death in the woods. Later, while breaking into Betty’s apartment to steal her diary, he kills her roommate when she comes home. Finally, he stalks and makes obscene phone calls to Detective Leo Kessler’s daughter Laurie, and at the film’s climax, murders all three of her roommates before chasing her down the street with a knife, all while in the nude. When confronted, Warren shows no remorse and promises Kessler that he'll come back.
• Harsher in Hindsight: One could argue that Warren Stacy was the proto-Incel, after the 2014 Isla Vista shooting, 2018 Toronto van attack, and the 2021 Plymouth shooting. Like Elliot Rodger, he was not even unattractive, but his predatory behavior was instantly noticeable and off-putting and disgusted everyone around him. Then, he stabbed the women who rejected him to death.
• Hilarious in Hindsight: Character actor Gene Davis plays a fully-unclothed Serial Killer who gets killed by a police officer played by Charles Bronson. Three years later, Davis would inversely play a fully-clothed blue denim clad police officer who gets killed by a Serial Killer in another crime thriller The Hitcher.
• Retroactive Recognition: Kelly Preston is one of Warren Stacy's victims near the end of the film.
