* AwesomeMusic: [[http://www.youtube.com/watch?v=Tq4GdBfLjsg The main theme]] is considered one of the most bone-chilling pieces ever put on screen. What makes it all the more awesome is that John Carpenter, who did the music for the film, has stated that he cannot read or write sheet music, and plays entirely by ear. "Fortunately, I've got a pretty good ear."
* CompleteMonster: Michael Myers, a cold-blooded SerialKiller with a hatred of teenage sexuality and a fondness for carving knives. After killing his sister at the [[EnfantTerrible age of six]], Michael breaks out of prison as an adult and goes on a killing spree through his hometown of Haddonfield, on his way to kill his [[CainAndAbel surviving sister]], murdering three of her friends before targeting her. He's stopped, but the horror doesn't end there. Michael returns repeatedly, making numerous attempts on Laurie, her [[RevengeByProxy daughter Jamie]], and anybody else who gets in his way. Incapable of feeling empathy, and driven by a loathing of seemingly everybody he encounters, the [[ImplacableMan unstoppable]] and [[SilentAntagonist perpetually silent]] Michael helped to define the SlasherMovie as we know it, and remains one of the most bone-chillingly evil.
* CrossesTheLineTwice: Bob has this joke when he and Lynda are about to go into the Wallace house.
--> "First I rip your clothes off, then you rip my clothes off. And then we'll rip Lindsey's clothes off."
* EarWorm: That theme...
* EnsembleDarkhorse: Lynda gets the least screen time out of the three girls (disappearing for the second act) but is easily the most remembered - for her CatchPhrase "totally" and her {{Adorkable}} giggling.
* EvilIsSexy: When he's unmasked, Michael is surprisingly attractive. Naturally, [[KillItWithFire after the events of the sequel]], his face is never clearly seen again.
* FairForItsDay: Although the DeathBySex trope was codified here and slasher films became associated with only virginal girls surviving, Laurie is quite feminist. Notably despite being terrorised by seeing her friends' dead bodies, she's able to fight off Michael ''three times''. Although she's clearly scared, she doesn't fall apart and prepares to defend herself. She demonstrates that she'll do whatever she can to keep Tommy and Lindsey safe. Even if Loomis saves her from Michael the last time, ''he'' doesn't stop Michael either.
* MemeticBadass: Jamie Lee Curtis, thanks to playing the archetypal FinalGirl - and ''{{Film/Scream1996}}'' naming her the "scream queen".
* MemeticMutation: Debra Hill talks about sitting in a theatre while the film was showing, and loads of people saying "totally" whenever Lynda did.
* {{Narm}}:
** Laurie runs across the street with Michael stalking her. She runs up to the door of the house and reaches into her pocket to find the keys. Her line?
--> '''Laurie:''' ''The keys?'' '''''THE KEEEEYS?!'''''
** The theme is a bit overplayed in the beginning of the movie as well.
** There's also the scene of the kids bullying Tommy. Somehow a bunch of kids who can't be younger than ten going on about "the boogeyman" fails to be anything but hilarious.
** The...odd way Dr Loomis turns around to check on Marion Chambers after she gets out of the car.
* NarmCharm: The film has equal measures of IdiotPlot and PurpleProse, but MundaneMadeAwesome RuleOfScary overshadows them so much that they're all excused.
* OneSceneWonder: Bob is off screen for most of the film, only appearing for around ten minutes. But he's still memorable for a couple of good lines, and those funky glasses (which his actor still has to this day).
* RetroactiveRecognition: Michael Myers' actor, Nick Castle, would become a director and made films such as ''Series/TheLastStarfighter'', ''ComicStrip/{{Dennis the Menace|US}}'', and ''Film/TheBoyWhoCouldFly''.
* SeinfeldIsUnfunny: Even though Michael Myers came first, in the later sequels, he ends up seeming like a rip-off of [[Franchise/FridayThe13th Jason Voorhees]]. Also since all the cliches ''Halloween'' created (or in some cases popularized) have now become cliches they are no longer frightening.
* SpecialEffectFailure: When Michael smashes one of Marion's car windows, he obviously has a wrench taped to his hand.
* ToughActToFollow: Subverted with Creator/JohnCarpenter. Most of his films released afterward (''Film/TheThing1982'', ''Film/EscapeFromNewYork'' and ''Film/BigTroubleInLittleChina'' among them) were not critical or commercial successes but have had second life on home video and cable going on to become classics and VindicatedByHistory. ''Film/TheThing1982'' in particular is now considered a heavy contender for his best film.
* UnpopularPopularCharacter: Guess who. Everyone in the film hates/fears him, [[SerialKiller for obvious reasons]], but he is incredibly popular in the fandom.
* VanillaProtagonist: Laurie of course. She's the rule abiding good girl who prefers babysitting to parties, in contrast to her wilder friends. PJ Soles joked that Jamie Lee Curtis told her she was lucky she wasn't playing "the boring one". Still, Curtis uses her acting to make Laurie likable and she does still go MamaBear on Michael when he threatens the children.
