History Film / FridayThe13thTheFinalChapter

* DropTheHammer: When Jason grabs Tommy, Trish attacks him with a hammer.

* MamaBear: Trish in spades. When Rob gets killed she runs, but when Jason grabs her little brother, she [[DropTheHammer beats him mercilessly with a hammer]] and electrocutes him with a TV. Despite suffering a broken shoulder and completely exhausted from being chased by Jason, the minute she sees him again she grabs the machete and starts swinging.

* TokenMinority: The minor character Lainie, the female ambulance worker, is the only African American in the film's cast.

* BigNo: Nurse Morgan's gives one when she is about to be killed.

* CutPhoneLines: Jason cuts the Jarvis house's phoneline (by pulling the box off the outside wall) when Trish tries to call for help.

* DecoyProtagonist: Rob looks to be the main male hero of the film to work alongside FinalGirl Trish. Instead he dies almost immediately after encountering Jason, with the real Final Guy of the film being Tommy.

* DoesHeHaveABrother: When Paul and co. pass an overweight hippie hitchhiker on their trip to Crystal Lake, Ted mockingly yells at her if she has a sister. She responds by flipping around her "Canada and Love" sign and showing them the other side which reads "FUCK YOU". And then she gives them [[FlippingTheBird the bird]].

* ExtremeMeleeRevenge: When Tommy kills Jason it seems it's all over and hugs Trish. However when Jason tries to pull a NotQuiteDead, Tommy pushes Trish out of the way and continues to chop at Jason, [[HeWhoFightsMonsters Trish helplessly begging him to stop.]]

* {{Foreshadowing}}: The poster shows the hockey mask with a knife on its left eyesocket. Jason is defeated with a machete going through his left eye.

** Tommy's tinkering with the car and other electronics was meant to be this. The original script called for him to turn the family microwave into some sort of ray gun and cause Jason's head to explode, a special effect at which Tom Savini excelled. The ending was rewritten when it was feared the microwave of doom could come off as too silly.

* LetsSplitUpGang: Trish and Rob split up to search the teenager's house, when they know Jason is there. Trish goes upstairs, while Rob goes to the cellar.
* MacheteMayhem: Unlike the popular portrayal, Jason doesn't use one at all. Instead it's used by Rob, and later by the Jarvis siblings.

* TookALevelInBadass: Tommy whom started out as a typical annoying kid who screamed and panicked when Jason grabbed him, ends up being the one to kill Jason. And for good measure he chops away at him to make sure he stays dead.
* TraumaticHaircut: Tommy shaves his head to give himself the appearance of younger Jason, so that he can confuse him.

* JerkassHasAPoint: While Ted is a jerkass, he does give Jimmy useful advice to get him laid. [[DeathBySex Too bad neither of them lasts long after.]]

* TooDumbToLive: Rob and Trish, shortly before their deaths. They split up instead of investigating together, Trish sees Doug's corpse and decides to scream and run frantically despite knowing Jason is lurking around, Rob goes back down the stairs to retrieve a small knife without using the flashlight he had earlier, he then gives up against Jason without bothering to fight back -- a stunning display of the trope, compared with Rob's earlier competency. Trish stands there dumbfounded with a machete in her hand and doesn't come to Rob's aid, and slowly walks back down the stairs even though she ''just saw'' Jason killing Rob. It's amazing they weren't killed sooner.

* AnAxeToGrind: Jason kills Sara by throwing an axe at her through a door.

The fourth film in the ''Franchise/FridayThe13th'' film franchise.

* DramaticUnmask: Jason deteriorating face is revealed when Trish strikes him with a machete.

* TheCameo: Chris Higgins briefly appears in the hospital where Jason's body is sent to, along with her parents. It appears Chris had managed to stop laughing after her manic fit at the end of the previous movie.
** WordofGod says that the character crying in the hospital is not Chris, but just a random parent of one of the murdered kids.

* RasputinianDeath: Keeping in mind this and the previous two films ''all'' take place more or less back to back, Jason took having a machete driven into his shoulder, being hung, an ax slammed into his skull, getting hit in the head with various blunt objects, and finally gets a machete driven through the side of his head which finally kills him. When his hand twitches again, Tommy proceeds to chop into him repeatedly to make sure he's dead.

As per the title, the film was [[SeriesFauxnale supposed]] to be the grande finale to the series. But less than a year later, [[Film/FridayThe13thPartVANewBeginning another sequel was released]].

& LetsSplitUpGang: Trish and Rob split up to search the teenager's house, when they know Jason is there. Trish goes upstairs, while Rob goes to the cellar.

* CutPhoneLines: Jason cuts the Jarvis house's phoneline when Trish tries to call for help.

* ImpaledWithExtremePrejudice: Jason kills Terri by impaling her with a wooden pole, which he then uses to stick her to the side of the house.

* ImpaledWithExtremePrejudice: Jason gets a machete in the eye. And falls all the way to the handle, making it impale its eye. He also kills Terri by impaling her with a wooden pole, which he then gets stuck with her body against the aide of the house.

* DarkerandEdgier: This is often considered to be the darkest entry in the series due to the intense tonal shift (especially compared to ''Part III''), the dark atmosphere, and the intensity of some of its death scenes.

* RevealingHug: At the end, as Tommy and Trish embrace, Tommy [[TheEndOrIsIt glares menacingly at the camera]].

* TooDumbToLive: [[spoiler: Rob. When he and Trish leave the basement, Jason tries to grab her ankle from underneath the stairs. So Rob grabs the machete and runs down... all the time being turned ''away'' from the space under the stairs where he ''knows'' Jason is, just asking to be attacked from behind. Jason does not miss this opportunity. Compared with Rob's earlier competency, this comes out as a stunning display of the trope.]]
** [[spoiler: It is Rob's foot that gets stuck in the staircase, and Trish is holding the machete. Rob drops a small knife, and it isn't implied that Jason causes him to trip. This trope, however, is displayed throughout the sequence leading up to Rob's death, by both Rob and Trish: they split up instead of investigating together, Trish sees Doug's corpse and decides to scream and run frantically despite knowing Jason is lurking around, Rob goes back down the stairs to retrieve a small knife without using the flashlight he had earlier, he then gives up against Jason without bothering to fight back, Trish stands there dumbfounded with a machete in her hand and doesn't come to Rob's aid, and lastly, Trish slowly walks back down the stairs even though she ''just saw'' Jason killing Rob. It's amazing they weren't killed sooner.]]

* FinalGirl: Trish.

* GenreSavvy: Tommy. When he sees Jason's [[FingerTwitchingRevival fingers]] [[NotQuiteDead start]] [[OnceIsNotEnough twitching]] after he's supposedly been defeated, how does Tommy respond? By completely ''flipping out'' and [[ExtremeMeleeRevenge going to town on Jason]] with a machete until there's no longer ''any'' part of him that's moving.

The film starts [[ImmediateSequel right after the events]] of ''[[Film/FridayThe13thPartIII Part III]]'', with Higgins Haven crawling with police and paramedics. The bodies are taken to the morgue, NotQuiteDead Jason Voorhees among them. As soon as he's put into the cold, he spings back to action. With the killing spree continuing, he starts targeting an area near the Crystal Lake where the Jarvis family lives, with a group of teens also present to provide some cannon fodder.
