As You Know: Averted; significant bits of exposition are given to us in the form of the other characters telling David things he bloody well should know, but doesn't because he wasn't there when he was needed.
Still, some of the exposition does come off as stilted and forced, with characters going out of their way to explain their relationships with each other. Surprisingly averted with Olivia, who barely has a line until halfway through the movie with pretty much no explanation of the nature of her relationships with the characters. For instance, David's first scene where he interacts with her involves tending to her wounds and calling her baby, which turned a few heads at the theater
Breaking Speech: The deadite possessing Mia gives David one for abandoning his sister and his dying mother years ago.
Bring My Brown Pants: When Olivia starts to lose control and become possessed we see her urinate on herself when she realizes that she's about to cut her face off.
Call Back: The film has several to the original film, including Sam Ramni's Oldsmobile parked outside the cabin, Deadite Cheryl's death threat being heard during Mia's possession, and Professor Knowby's original tape recording playing at the end of the credits.
The Cameo: Bruce Campbell as Ash appears in a post-credits scene.
Darker and Edgier: After an increasingly comedic trilogy, this film is fairly jarring in tone. It edges pretty close to Torture Porn as the main characters mutilate themselves and each other, the teenagers aren't at the cabin for a party, it's nearly devoid of jokes or one-liners, and it's entirely lacking the original trilogy's camp value.
Reconstruction: The Evil Dead was a pretty straightforward horror movie with little humor, and the camp came in more and more in the sequels. This film just goes back to the mood of the first film.
Dodge This: "Feast on this motherfucker" shoves the chainsaw into the Abomination's mouth.
Duct Tape for Everything: David uses duct tape for first aid to tape gauze onto stab wound, wrap up an amputation site, and in the makeshift defibrillator he uses to revive Mia.
Evil Laugh: Deadite Mia gets a very quiet and menacing one.
Expy: In the end, we get an evil version of Mia, which seems to be the Bad Ash of the new series.
Forging Scene: David rigging the hypodermic needle-defibulator in the remake.
Genre Blindness: Eric is the one who decided to unwrap a package wrapped in garbage bags and barbed wire. Even after he realizes the book is bound in human skin and has very apparent warnings that the book shouldn't be tampered with including:
Don't say it, Don't write it, Don't hear it!
Ironically enough this same character turns Genre Savvy when things start going to hell and is the first one to realize and come to terms with what is really going on. Granted this is mostly due to the knowledge gained from having read the ill-fated book, as well as knowing that his reading from the book was the reason it all started.
Girl-on-Girl Is Hot / Double Standard: Rape, Female on Female: Horrifically inverted, in the scene where the possessed Mia pulls Natalie into the cellar and begins licking her legs, then splits her own tongue with a knife and force-kisses Natalie. It's just as sickening and violating as it should be.
Heroic Sacrifice: David gives up his life to save Mia from Deadite Eric. Turns into Stupid Sacrifice right after when we learn that this fifth death fulfills the conditions for the abomination to enter our world, leaving Mia all alone against a much greater threat. Possibly Played Straight since David was quickly bleeding out and Deadite Eric's "He's coming" line implies the conditions were already met.
Hope Spot: Natalie looks like she's made it out of the cellar, despite the broken step, until Mia grabs her ankle at the last second and drags her back down.
Humanoid Abomination: The creature that rises up from hell in the finale of the remake, which is basically a lanky demonic form of Mia. It's even called "The Abomination."
Licking the Blade: Taken to extremes, when Mia licks a utility knife and then presses her tongue into the edge hard enough to slice her tongue in half down the middle.
Loophole Abuse: The only way to cleanse someone of the Evil is the kill them via immolation, dismemberment, or live burial. However, with careful planning and an improvised Magical Defibrillator, David manages to exorcise Mia and successfully bring her back to life.
Made of Iron: Eric, full stop. Let's count 'em up, shall we? Knife in the chest, needle to the face, NAIL GUNNED, crowbar to the arm, crowbar to the head, and he STILL risks his life trying to save his friend.
Magical Defibrillator: David shocks Mia back to life with a car battery charger wired to a pair of syringes.
Oh, Crap: Natalie's face when she realizes Mia has just grabbed her ankle.
Rasputinian Death: Eric qualifies as this. He first falls and hits his head on the sink with enough force to break it, suffers a stab wound on his chest dangerously close to where his heart ought to be as well as multiple stabs from a syringe to the face, the needle breaking off and becoming embedded dangerously close to his eye. Some time later he gets attacked with a nail gun and gets more than a few in his arms, body and face. Soon after he gets attacked with a crowbar and nearly breaks his arm trying to block it, as well as getting a few full blows directly to his head. Despite this he still manages to make his way to the basement from the outside and save David from the possessed Mia, at which point she stabs Eric fatally.
The Stinger: Ash appears at the end of the credits to say one of his signature lines. "Groovy"
Trailers Always Lie: The trailer includes several clips that don't appear in the finished movie, including David messily attacking someone with a chainsaw and Mia chanting the possessed Linda's song from the original.
Vomit Indiscretion Shot: Mia does this twice. When the cravings are getting to her, she's outside the cabin walking around in circles, she vomits after a while. Later when she gets possessed, she projectile vomits blood all over Olivia.
You Cannot Grasp the True Form: Mia gets several looks at the Force (the disembodied thing flying around the woods), and sees a demonic version of herself. Later, just before Olivia gets possessed, she sees a similarly monstrous version of herself in the mirror. "The Abomination" may also count, as Mia is the only one there to see it and it looks somewhat like her, or it could just be that the Abomination took the form of the first person to be possessed.
