* AlternateCharacterInterpretation : Notice how [[https://youtu.be/2PU-dGTWabQ Freddy's face]] goes from his usual SlasherSmile to a mixture of seriousness and confusion after Kia calls him the other F-word. One could probably imagine that he was thinking "[[WhatTheHellHero Bitch, what is wrong with you]]?! [[EvenEvilHasStandards Even]] '''[[EvenEvilHasStandards I]]''' [[EvenEvilHasStandards wouldn't sink so low as to use homophobic slurs]]!"
** Or he was mad that she was accusing HIM of being gay... something that in the 70s would be looked at with disdain and hatred and knowing Freddy he'd HATE being compared to them.
* ArtisticLicenseGeography: Springwood is in Ohio. Crystal Lake is in New Jersey. Originally there was supposed to be a sequence to show them driving all night to show how long it took for them to get between the locations. But the way the film was cut in the final production, it gives the impression that the towns are side by side.
* AwesomeMusic: ''How Can I Live'' by Ill Nino.
* BaseBreakingCharacter:
** Lori Campbell. Some think she's among the worst [[FinalGirl Final Girls]] in the series, if not ''the'' worst, because of Monica Keena's notoriously poor performance and the character being a very shallow stereotype. Others think she's a very brave and likable girl who manages to become a badass at the end.
** [[SassyBlackWoman Kia]] as well. Some viewers very much enjoyed Creator/KellyRowland's LargeHam performance and found the character to be both amusing and likeable. Others found her to be nothing more than a grating, poorly written stereotype and felt Kelly's performance was amongst the worst in the movie, not to mention that she casually called Freddy a faggot.
* CriticProof: Despite being bashed by critics, this is the highest-grossing film in the history of both franchises (or at least the Friday the 13th franchise, since the [[Film/ANightmareOnElmStreet2010 Nightmare reboot]] outgrossed this one).
* CultClassic: Being a crossover film featuring two iconic horror villains does that.
* EnsembleDarkhorse: Gibb (due to being played by popular scream queen Katharine Isabelle) and [[TheStoner Freeburg]] (because of his hilarious one-liners) tend to be the best received of the teens.
* EpilepticTrees: The film's ending generated a lot of WildMassGuessing; Ken Kirzinger (Jason's actor) mentioned in the commentary that a fan had asked him if the ending represented [[AscendedDemon Jason going to Heaven]].
* HilariousInHindsight:
** See that ''Franchise/MortalKombat'' shout-out on the main page of the movie? It's amusingly prophetic because with the announcement of the first DLC character for ''VideoGame/MortalKombatX'', Freddy and Jason have appeared in the ''Mortal Kombat'' series, in that order. ''VideoGame/MortalKombat9''' for Freddy and ''VideoGame/MortalKombatX'' for Jason.
** Jason Ritter stars in a story about a TownWithADarkSecret, with a parent who knows more than he seems to and is pretending the mysterious supernatural force in the town isn't real to protect his family? There's an FauxAffablyEvil demonic entity with a [[EvilHasABadSenseOfHumor twisted sense of a humor]] and a NiceHat who enters peoples dreams to torment them? Are you sure this isn't ''WesternAnimation/GravityFalls''?
* InternetBackdraft: The news that Jason would not be played by Creator/KaneHodder generated a ''huge'' uproar in the fanbase. Flame wars still persist to this day between fans who feel that Ken Kirzinger's greater height made him a more intimidating opponent compared to Freddy, and those who feel that he was an adequate at best replacement and that Hodder would have played the role better. Things have been made worse for the latter group by the next entry being a ContinuityReboot, pissing them off that Hodder couldn't be around for the original version's final outing.
* JustHereForGodzilla: Most people watch this film just for the fight, ignoring the forgettable humans entirely. It doesn't help that each character's name is only said a few times (if at all).
* MemeticMutation: Ever since this movie, multiple people within the NightmareOnElmStreet comics, as well as members of various horror fandoms, have taken to using "butter knives" as the go-to insult for Freddy's WeaponOfChoice.
* MoralEventHorizon: Setting Jason on Springwood was bad enough, molesting Lori with a tongue kiss was more disturbing, but Freddy shows how depraved he can be when he reveals [[spoiler:not only did he kill her mother, but afterwards decides to rape Lori before killing her as well.]]
** Though to be fair Freddy gleefully skipped over the Moral Event Horizon line some six movies ago. He's probably one of the most purely evil slasher villains to ever grace the silver screen.
* {{Narm}}: The title itself. If you hear it not knowing it's referring to ''that'' Freddy and ''that'' Jason, it sounds like the name of a contemporary stoner comedy.
* RetroactiveRecognition: Mark's dead brother is played by the bully from ''Film/AChristmasStory''.
** Will is played by Jason Ritter, the future voice of [[WesternAnimation/GravityFalls Dipper Pines]].
* TheScrappy: While most characters have a few fans, no one likes Will. Jason Ritter's poor acting (to the point of smiling when his friends are dying) tends to be the biggest reason why.
* SpiritualSuccessor: Or is it Spiritual ''Predecessor''? In November 1984, ''Fangoria'' magazine ran a 5-page color comic strip entitled "1st ''Fangoria'' Splatterbowl," by comic artists John Arnold and Linwood Sasser, wherein [[Franchise/{{Halloween}} Michael Myers]] took on Jason Voorhees and [[Franchise/TheTexasChainsawMassacre Leatherface]].
* {{Squick}}:
** Freddy kissing Lori in the form of her father, complete with sticking his tongue in her mouth.
** Freddy lifts [[spoiler:Lori]]'s skirt with a clear intent to rape her.
* {{Tearjerker}}: On a meta level, "And Robert Englund as Freddy Krueger" has become this in hindsight, knowing that this was the last time that long-familiar credit will appear.
* TheyWastedAPerfectlyGoodCharacter:
** Blake. Immediately after losing his best friend, Trey, and swearing revenge on Trey's killers... he's unceremoniously killed off by Jason.
** Mark. All we know about him is his brother was killed by Freddy, and he's on the up-and-up as far as the lore goes. He could have explained Krueger's MO and how to stop him to the others instead of their figuring it out in the forced, unlikely way they did.
* TheWoobie: Jason as he's being [[MindRape mind raped]] by Freddy in the dream world. As he's forced to relive his ill-fated drowning way back in Camp Crystal Lake. He's even reduced to the scared child that he is, with Freddy going so far as to rip off Jason's hockey mask and call him an [[KickTheDog ugly piece of shit]]. Not just that, but before his first fight with Freddy begins, the latter yells him while he's disguised as Jason's mother, ranting about how disappointed "she" is that Jason didn't stop killing. Poor Jason even gasps in shock, thinking that he really did disappoint Pamela. [[EvenBadMenLoveTheirMamas Making his mother]] [[SoProudofYou proud of him]] has been his driving purpose as a mass serial killer, so hearing these words must have broken his heart, before he realized that Freddy was just using his mother's image to trick him into killing people.
