YMMV / Knock Knock (2015)

• Alternate Character Interpretation:
  • Bel. Is she an Ax-Crazy sadist like Genesis, or a damaged person going along with it? When she roleplayed as a molested child was she trying to mess with Evan's head, or was she acting out a childhood trauma?
  • Eli Roth's commentary on the alternate ending describes the girls as having "switched roles." However, Bel is still the one getting up close and intimate with the new victim, and Genesis is still the one standing back and talking, exactly the same dynamic they had with Evan.
  • In the alternate ending, is Evan going to save the next victim and prove his innocence, or put a more permanent ending to the girls' rampage? The answer may be subtly hinted at by the fact that Evan puts his gloves on before entering the house.
• Best Known for the Fanservice: Lorenza Izzo and Ana de Armas' nudity is very often mentioned in reviews.
• Fan-Preferred Cut Content: Most people prefer the alternative ending over the original ending as it would've made this movie one of the few where it was heavily implied that the Double Standard Rape: Female on Male wouldn't have ended with the two women being Karma Houdinis which is something that has never been done in movies before.
• Fridge Horror:
  • Bel and Genesis get away with ruining Evan's life... except they were sloppy enough to leave evidence all over the place that there had been a break-in, and Evan could easily say he'd been coerced into sex with them. But... exactly how many girls out there are legally named "Bel" or "Genesis"? Most likely, they'd used aliases to cover their tracks. Although while the alternate ending shows that they've been wearing wigs, as they swapped them when they moved onto their newest victim, facial recognition technology could most likely sort everything out when the police inevitably get involved.
  • When Bel raped Evan, she was also wearing his daughter's elementary school uniform and role-playing Parental Incest, which might mean that after Genesis posts the video of it to Evan's Facebook, in addition to being framed as a willing adulterer in this instance, Evan may have also been Mistaken for Pedophile.
  • Check out Evan in the alternate ending. His hair has grown back and his beard is longer. He's been tracking these girls for a while, but that would imply that he's suddenly got a lot of free time on his hands. Odds are his wife found out about the sex and kicked him out of the house, which will make his revenge even stronger.
• Ham and Cheese: Keanu Reeves's performance whenever he's meant to be anything other than calm or cheerful. All the more appropriate that he compares a two-girl blowjob to "free pizza". In his defense, at least he's not saying "whoa".
• Memetic Mutation:
  • A buried Keanu Reeves looking at his phone and him responding with a Skyward Scream is often used as a reaction to something awful.
  • This movie has been referred to as "Eli Roth's threesome fantasy with his wife and Ana de Armas" more than a few times on places such as Reddit.
• Moe: Bel is a total cutie and is played by Ana de Armas, who a few years later would go on a tear of critical acclaim for playing adorable characters. That still doesn't negate that Bel here is a total psycho.
• Moment of Awesome:
  • Louis realizing that Bel and Genesis are torturing Evan and not falling for their wiles as easily as they'd hoped. Too bad he gets killed anyway.
  • The alternate ending implies that Evan will get some sweet, sweet payback.
• Narm:
  • Some of the movies' quotes are regarded as this, most notably "Chocolate with sprinkles" and Evan's rationalization to sleeping with the girls in his "The Reason You Suck" Speech to them.
    "IT WAS FREE FUCKING PIZZA!"
  • Evan's Skyward Scream at the end, which he delivers while gagged. Given that it's Keanu Reeves, you almost expect him to fire a gun in the air, except he's buried up to his neck.
  • There are two laughably odd moments in the otherwise horrific scene where Bel rapes Evan. First, Genesis calls out for Bel to do it "doggy style," while Evan is tied to the bed and Bel is on top of him. Second, Bel responds to this by... barking and howling. Very realistically, with what is an obvious sound-effect. Apparently "doggy-style" means something entirely different to Genesis and Bel!
  • There are so many nude scenes and close-up shots of Bel and Genesis's breasts and butts that it becomes excessive and quickly feels less like the characters taunting Evan and more like the film is desperately trying to milk as much fanservice from the actresses that they can, especially when compared to Evan's Right Through His Pants treatment in the sex scenes.
• Narm Charm: By all accounts, Evan's "free pizza" speech is often considered the best scene in the movie solely for how much Keanu Reeves hams it up to hilarious levels, to the point some even see it as proof He Really Can Act.
• Paranoia Fuel: Imagine leaving the house for the weekend, only to come home and find every square inch of it has been either vandalized or wrecked beyond repair.
• Retroactive Recognition: This was one of the first starring roles for Ana de Armas, who would become MUCH more famous by the end of the decade for her performances in Blade Runner 2049, Knives Out, and Blonde.
• So Bad, It's Good: What ultimately draws audiences in. Eli Roth, Keanu Reeves and a plot that combines Fatal Attraction with Funny Games ultimately forms a thriller that gets more laughs than gasps.
• Stoic Woobie: Evan can do nothing but watch as Bel and Genesis destroy his home. Any time he tries to get help, he only makes them angrier.
• The Woobie: Louis, the art dealer who comes to collect Mrs. Webber's latest sculpture only to run afoul of the girls. Once they realise he's not going to fall for their charms, they steal his inhaler and toss it back and forth while he chases after it, getting closer and closer to an asthmatic attack. He then slips and hits his head on a sculpture, snapping his neck. Bel and Genesis then dump his body.
