* CompleteMonster: The SerialKiller loves playing cat and mouse games with his victims. He infiltrates a group of FBI profilers during a field mission to a deserted island with a makeshift town used as a training ground by the bureau, where they must solve a case involving a fictional serial killer called "the Puppeteer" organized by their supervisor. He sets the island up with an array of boobytraps and puzzles to kill them while watching from within the group to turn them against each other and [[HuntingTheMostDangerousGame give himself good sport]]. His more cruel murders include a victim getting slowly killed with liquid nitrogen from the feet up, and another one burned to death from inside through acid-laced cigarettes. [[spoiler:He kidnaps the supervisor (who had been monitoring the group in secret) to an abandoned warehouse on the other side of the island where he proceeds to torture him for days before [[DeadGuyPuppet preparing his corpse and hanging it up for the trainees as a sort of perverse puppet]].]] It's only after his identity as [[spoiler:Sarah's best friend Lucas]] is revealed that the true level of [[ManipulativeBastard his manipulation]] becomes apparent, and he frankly admits he started his string of murders 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.
