* CompleteMonster: The mysterious {{serial killer}} loves playing cat and mouse games with his victims. He infiltrates a group of trainee FBI profilers on a field mission to a deserted island used as a training ground by the bureau, where the trainees must solve a case involving a fictional serial killer called "the Puppeteer." The killer sets the island up with [[RubeGoldbergHatesYourGuts an array of booby traps and puzzles]] to kill them while watching from within the group to turn them against each other and [[HuntingTheMostDangerousGame give himself good sport]]. His cruelest murders include a victim being slowly [[KillItWithIce killed]] with [[LiterallyShatteredLives liquid nitrogen]] from the feet up, and another one burned to death from the inside out through acid-laced cigarettes. He kidnaps the trainees' supervisor (who had been monitoring the group in secret) and proceeds to [[ColdBloodedTorture torture him]] for days before preparing his corpse and hanging it up for the trainees to find as a sort of [[DeadGuyPuppet perverse puppet]]. It's only after his identity as [[spoiler:Sarah's best friend Lucas]] is revealed that the [[ManipulativeBastard true level of his manipulation]] becomes apparent, and he frankly admits he started his murder spree by [[SelfMadeOrphan killing his parents as a child]] and now simply enjoys a good hunt for new and more intelligent victims.
* HilariousInHindsight: The last three standing in this murder mystery have all headlined recent Creator/{{CBS}} hit mystery shows: Kathryn Morris in ''Series/ColdCase'', Music/LLCoolJ in ''Series/NCISLosAngeles'', and Creator/JonnyLeeMiller in ''Series/{{Elementary}}''.
* NightmareFuel:
** The deaths are all pretty nasty, but one can imagine parents using a certain scene from this film to [[SpaceWhaleAesop warn their children about the "dangers" of smoking]].
** Seeing [[spoiler: Harris]] strung up to the ceiling, hanging by his face and limbs with hooks and wires was bad enough, but an alarm goes off that causes his body to jerk around like a puppet while children's music creepily plays.
** The first murder, involving the victim getting sprayed with liquid nitrogen until they shatter into pieces, would not seem remotely out of place in a ''Franchise/{{Saw}}'' film.
* SpecialEffectsFailure:
** It was perhaps rather unwise of the creators to populate the fictional island with plastic mannequins, as it rather calls attention to when mannequins are used which are meant to be the characters' corpses. [[spoiler:Harris's corpse]] looks particularly shiny and unconvincing.
** The effects shot of [[spoiler:the boat exploding]] looks rather bargain-basement.
* TheyWastedAPerfectlyGoodPlot: FBI Agents isolated on an island facing a killer hidden among them who has studied them and preys on their psychological weaknesses? Definitely a cool concept. Too bad they follow it up with healthy doses of GambitRoulette, TheUntwist ([[spoiler: Seriously, did anyone expect LL Cool J to die? Or be the killer? Or NOT call Jonny Lee Miller as the killer?]]), and the IdiotBall.
