History Film / Mindhunters

* TenLittleMurderVictims: It was widely considered an unofficial adaptation of ''And Then There Were None''. That said, this case is a combination of Type B and Type K.

* TenLittleMurderVictims: It was widely considered an unofficial adaptation of ''And Then There Were None''.

** [[spoiler: J.D.]] getting his lower extremities practically flash frozen couldn't have felt that great.

* AgonyOfTheFeet: [[spoiler:Nicole]] smokes a cigarette, not knowing it has been laced with [[HollywoodAcid acid]], several drops of which eat through her boot. She briefly stomps her foot in pain [[OhCrap before realizing she has other problems]].

** It's soon established that the killer is using traps and schedules to knock off one or two members of the group at a time, and yet no one just considers staying put in the forensic room they know isn't trapped and just waiting the thing out. Sure, the killer is with them, but he's outnumbered and you'd think one person would figure out such a simple solution.

* DecoyProtagonist: [[spoiler:J.D.]] at a push. The actor who plays him is [[spoiler:definitely the most well-known of the main cast,]] with the possible exception of [[spoiler:Val Kilmer, who also ends up dead.]] WordOfGod is that no specific character was set up to be the lead, to give the impression that AnyoneCanDie.

* TheTeam: JD is TheLeader, Sara is TheChick and Gabe is the SixthRanger. Elsewhere Bobby is TheAce, Nicole shares TheSmartGuy role with him and also TheBigGuy with Vince. Lucas claims to be the best driver and Rafe isn't really developed enough to slot into a role.

* UndignifiedDeath: COmbined with DroppedABridgeOnHim in Harris's case; he gets tortured, forced to watch his students die off one by one, and then is murdered and grotesquely strung up like a marionette for the remaining survivors to find.

** Implied. Gabe notes that J.D.'s desire to be the leader was because he lacked one in his own life.

* AssholeVictim: [[spoiler:Vince]].

* BigBad: [[spoiler:Lucas Harper]], the SerialKiller stalking the island.

* * SacrificialLion: J.D. is the first one killed off to show that this isn't just a simulation anymore.

* SacrificialLion: J.D. is the first one killed off to show that this isn't just a simulation anymore.

* CruelAndUnusualDeath: If being sprayed form the feet up with liquid nitrogen until you [[LiterallyShatteredLives fall over]] or finding out the hard way that your smokes have laced with HollywoodAcid don't fit this trope, nothing does.

* FamousLastWords:
** "You." [[spoiler:Vince.]]
** "[[DefiantToTheEnd Well, go on and finish it]]." [[spoiler:Jake Harris.]]

* RedHerring: By the time the cast is whittled down to about five people, it's revealed that [[spoiler:Jake Harris, the supervisor,]] is the real killer when he begins to taunt them through the loudspeakers set up on the island. They find him inside his lair, [[spoiler:only to discover that the speakers were playing a pre-recorded tape and Harris himself had been tortured to death.]]

--> [[spoiler:'''Vince''']]: You.
--> [[spoiler:'''Jake Harris''']]: [[DefiantToTheEnd Well, go on and finish it]].

* OntologicalMystery: The movie has definite shades of this. The characters do know ''why'' they're on a secluded island: as part of an FBI profiler training exercise. It doesn't take long before they're completely cut of from the outside world and it turns out that there's a killer amongst them who starts murdering them one by one.

** Vince represents a different sort of Sloth. The trap with the water pipe banks on him not trusting anyone with his gun, which is moral laziness. [[spoiler: In this case he overcomes it and trusts Gabe]].

* SelfMadeOrphan: The killer when he was just a lad. He assumed the police would take him away when they investigated the scene, but to his astonishment nobody even suspected him of causing his parent's deaths, which just fed his misantropy even more.

* SelfMadeOrphan: The killer when he was just a lad.

* AgonyOfTheFeet: One of the female FBI agents smokes a cigarette, not knowing it has been laced with [[HollywoodAcid acid]], several drops of which eat through her boot. She briefly stomps her foot in pain [[OhCrap before realizing she has other problems]].

* FailedASpotCheck: In a DangerRoomColdOpen situation, two FBI trainees enter a house to save a serial killer's latest victim and declare the area safe before they're both "killed" by a second perpetrator. Their supervisor later chews them out about all the telltale signs they missed that the killer might have had an accomplice, including two cars parked in the front.

* {{Foreshadowing}}: Since the method of death is directly linked to the person's personality, this entire movie is foreshadowing from the get-go. The first two to three scenes set up the entire shaky house of cards. The only trap that isn't really foreshadowed is [[spoiler: Headless Coffee Guy]] (with a HandWave of another character referring to him as a [[spoiler:"coffee junkie"]] several hours later). Another major but subtle instance is [[spoiler:Agent Jensen describes Lucas as having an addictive personality. He's addicted to killing.]]

* BodyHorror: Nicole's death. Turns out that [[HollywoodAcid ac]][[PoisonIsCorrosive id]] ingested via cigs can do a little more than contribute to the chance of getting lung cancer...

* DeadpanSnarker: Gabe, Bobby, and Rafe.

** It takes [[spoiler: the killer and the last female standing]] several attempted gunshots to realize that firing underwater messes up your aim.

* KillItWithIce: In the first trap set by the SerialKiller, a victim's feet get blasted with liquid nitrogen; his ankles then shatter and he falls to the ground and crumbles.

* OneDoseFitsAll: At one point, the killer sneaks a sedative into the pot of coffee the team is drinking from. It takes effect a few minutes later and every team member is out cold within about a minute of each other, and similarly wake up within a minute of each other several hours later. Never mind the disparities in how much coffee each team member drank or that the team includes six team members ranging from a burly ScaryBlackMan to two petite women (however, [[spoiler:one of the team members gets murdered while asleep and another is the killer himself]], mitigating this slightly).

* {{Plothole}}: After repeatedly remarking that the simulation "doesn't feel real" without his gun, Vince pulls out and [[DramaticGunCock dramatically cocks]] a gun and he'd concealed in his wheelchair. All the other characters berate him for this, as they'd been specifically told not to bring weapons. However, just minutes earlier, Nic and LL Cool J's character can clearly be seen bearing handguns as they [[spoiler:carry JD's corpse.]]
