History Film / Meg2TheTrench

* ImpaledWithExtremePrejudice:
** The final wild meg [[spoiler:is killed when Jonas draws it towards him at an angle where it basically jumps onto the blade of a crashed helicopter, allowing Jonas to impale the meg through the mouth]].
** [[spoiler:Jiuming stabs a snapper in the side of the head with a broken shovel and stakes an improvised bomb onto the cryptid giant octopus. It does not kill it but likely it was wounded enough for Haiqi who it tried to kill to break free and finish it.]].

* DidntThinkThis Through: When Jonas and his team inadvertently catch sight of Montes' illegal mining operation at the bottom of the trench, he chooses to destroy all evidence and kill both Jonas and his teammates via detonating bombs. They cause a massive rockslide, but also disturb the mating megalodons, causing one to attack his submersible and leaving him stuck at the bottom of the trench as well.

* {{Foreshadowing}}: When [[spoiler: Driscoll]] is revealed to be a villain, Jiuming exclaims that "Karma will find you!" [[spoiler: She ends up meeting her demise at the jaws of the Snappers, creatures who her operations helped stir up.]]

* FanserviceExtra: On the pleasure island sequence, the audience is treated to a number of Chinese women with rather large breasts in swimwear.

** The Tyrannosaurus Rex seen in the opening sequence is a dead ringer for the T-Rexes from Franchise/JurassicPark, right down to the color scheme. The Megalodon breaching up behind it and dragging it down into the depths is a rather obvious riff on the Indominus' death scene in ''Film/JurassicWorld''.

* KilledOffscreen: [[spoiler:Lance gets killed offscreen only his terrifying scream can be heard and helmet can be shown afterwards]].

* AmbiguousSituation: In the final encounter with Haiqi, [[spoiler:Jiuming is certain he sent her away on his own, but Jonas observes that it's more likely she's chasing the nearby dolphins]].

* ArtisticLicenseBiology: The Megs being able to survive swimming at the surface just as well at the ocean floor is already pushing realism, but the Snappers being portrayed as equally agile ''running on land'' as swimming 25,000 feet below sea-level is plainly ludicrous.

** There's quite a disturbing shot during the Fun Island attack sequences where we see the perspective of the holiday-makers the shark has swallowed from ''inside its mouth''. It's bloodless, but also definite NightmareFuel as those people are seconds away from being actually swallowed into oblivion.
* SuddenSequelDeathSyndrome: [[spoiler: Jonas' love interest Suyin has passed away between the first movie and this one. The circumstances are left vague but Jonas is now raising her daughter himself.]]

* ArtisticLicenseBiology: The Megs being able to survive swimming at the surface just as well at the ocean floor is already pushing realism, but the Snappers being portrayed as equally agile ''running on land'' as swimming 25, 000 feet below sea-level is plainly ludicrous.

** No, you cannot just "breathe all of the air out of your skull" and be able to free-swim at ''25,000 feet below sea level wearing no suit.'' But since the movie's premise is already 100% scientifically impossible, so the film just leans into its own absurdity with this particular subplot and expects the audience to take it in stride.

* PoweredArmor: Jonas and his team brave the trench with armored diving suits with hydraulic strength enhancements [[spoiler:after Montes' explosives lead to their subs being destroyed]]. Of course, that leads to some of them becoming monster chow.

* ImpaledWithExtremePrejudice: The final wild meg [[spoiler:is killed when Jonas draws it towards him at an angle where it basically jumps onto the blade of a crashed helicopter, allowing Jonas to impale the meg through the mouth]].

** Jess is treated as someone who has been with the team for a very long time yet was only introduced in this film

* DroppedABridgeOnHim: Meiying's mother Suyin has [[spoiler:died in the interval between the two films, with Jonas PromotedToParent as a result. It's never explained exactly what happened, just that she'd passed in 2021.[[note]] Considering Suyin is the counterpart to Terry Tanaka from the novels, it was probably cancer.[[/note]]]].

* AdaptedOut: Sadly, the Kronosaurs from the equivalent Steve Alten book are removed in favour of the smaller Snappers - an effective menace to the characters on land but far from the challenge to the giant sharks the Kronosaurs were.

** [[spoiler:Jess, who betrayed her team and showed no remorse for the deaths of three people, gets swallowed whole by a Meg after assuring herself she was behind Meg-proof glass]].

* BitchInSheepsClothing: [[spoiler: Jess starts out as an affable Mana One tech that everyone seems to get along with; about halfway through she reveals herself as TheMole, working alongside Driscoll and Montes to illegally mine the trench for rare minerals, showing no remorse when her actions get Lance, Sal, and Curtis killed, and actively trying to murder Jonas and his surviving crew after her attempt to strand them fails.]]

* HopeSpot: [[spoiler: Curtis survives the rest of the journey back to the station after her helmet gets damaged by a Snapper but it implodes on her before the decompression process can be completed.]]

* ExplosiveDecompression: Inverted both ways. [[spoiler: Curtis's helmet ''implodes'', compressing around her skull after taking integral damage at depth and it happens gradually enough that she survives the journey back to the station but her companions are forced to watch it happen while Jiuming futilely tries to reassure her.]]

* AnkleDrag: [[spoiler: Driscoll's final moments consist of a Snapper dragging her kicking and screaming by one of her ankles from her helicopter and into some nearby brush where it and its fellows start feasting on her.]]

** [[spoiler:Montes]] dies after Jonas actually ''kicks'' him into the Meg's mouth, complete with a shot of his legs twitching as the shark chomps down on them. [[spoiler: Sal]] suffers a similar fate early on, ironically while ''throwing herself'' into the Meg's path to save someone else, and it's made worse by the fact that it happens several thousand feet underwater so she would have suffered compression trauma when the Meg bit through her suit.

* HeroicSacrifice: [[spoiler:Sal]] pushes Jimmy out of the way as a Meg bares down on both of them, resulting in their death.

* AnkleDrag: [[spoiler: Driscoll's final moments consist of a Snapper dragging her kicking and screaming by one of her ankles out of the helicopter and into some nearby brush where other Snappers quickly join in on the feast.]]
