What parents need to know

Positive messages

The movie indulges in intolerance and vengeance, with no concept of understanding or empathy.

Positive role models

Two characters act cruelly and out of vengeance and self-righteousness. A third character is an accused pedophile, though viewers don't know the details of his crime. He seems to be a good father and husband, except that he succumbs to the other two main characters' charms and cheats on his wife.

Violence

A man is tied up, taunted, and abused. A man fights with and hits women, starting to choke one of them. Head-bashing. A man is stabbed in his already-wounded shoulder. Gun is drawn but not fired. References to statutory rape.

Sex

A man cheats on his wife with two women at the same time; both of them show naked breasts and bottoms. A long sex scene includes flesh-on-flesh close-ups. Oral sex. Husband and wife kiss in bed. Plenty of sex talk. Talk of sex with underage girls.

Language

Constant extreme language includes "f--k," "s--t," "c--k," "c--t," "a--hole," "goddamn," "whore," "bitch," "retarded," "hell," and "Jesus" (as an exclamation).

Consumerism

Apple computer, iPhones shown. Facebook mentioned. Uber mentioned. iPad mentioned.

Drinking, drugs, & smoking

Some background drinking and smoking. A character nearly smokes pot but stops. Talk of pot-smoking.

Parents Need to Know

Parents need to know that Knock Knock is a home invasion thriller that also deals with pedophilia, torture, and revenge. Women's naked breasts and bottoms are seen, and there's an extended three-person sex scene that includes implied oral sex and skin-on-skin close-ups, as well as plenty of sex talk. A character is tied up and abused, and a man fights with women. A gun is pulled but not fired. Language is extremely strong, with uses of "f--k," "s--t," "c--k," "c--t," and much more. There's some background drinking and smoking, and pot is shown and referenced. Fans of popular horror director Eli Roth (and star Keanu Reeves) will want to see this, so beware.

What's the story?

Architect Evan (Keanu Reeves) is a happy family man who has been in some kind of trouble in the past, but his artist wife and their two kids appear to have forgiven him. One weekend, he stays home to work while they go to the beach. But during a rainstorm, two young women who claim to be lost knock on his door. Genesis (Lorenza Izzo) and Bel (Ana de Armas) seem nice at first, and Evan lets them dry off and warm up while they wait for an Uber. Eventually the women get flirty, and the trio tumbles into bed together -- but the next morning, Genesis and Bel act crazy and won't leave. Things turn dark when they attack Evan, tie him up, and torment him. At first Evan thinks only of saving his marriage, but soon he becomes invested in saving his life.

Is it any good?

QUALITY

Director Eli Roth returns with another loathsome movie, this time gleefully playing around with a home invasion, torture, pedophilia, and revenge but never seeming to know what he wants to say. Details of Evan's supposed pedophilia are kept from viewers, so we have no idea just how bad his crime was -- only that his wife and kids seem to have forgiven him. He does make a big mistake by jumping into bed with Genesis and Bel, but he more or less earns our sympathies.

This brings up the question of why the two women would degrade themselves by sleeping with someone they intended to torture. Other inconsistencies come up, too, but eventually it all collapses into a dumb torture show with characters acting, by turns, vicious and stupid. KNOCK KNOCK is a huge waste of time and effort for Reeves (what was he thinking?); at least cinematographer Antonio Quercia chooses smooth, fluid camerawork over his usual jerky stuff.

Families can talk about...

  • Families can talk about Knock Knock's violence. Does the violence directed toward woman seem stronger than the rest? What message does that send? What's the impact of media violence on kids?

  • Why would Evan choose to have sex with his female visitors? What does he risk? How is sex portrayed in the movie?

  • Who has our sympathies in this movie? Why? Are any of the characters at all admirable?

  • Does the movie glorify drinking, smoking, or drug use?

Knock knock movie

Knock knock is directed by the controversial Eli Roth surprisingly this movie is his best the actors are amazing but parents BE WARNED: the content in this film is graphic in nudity, sexuality, violence, and language...there are graphic 3 way sex scenes that feature breast, bare bottoms, brief glimpses of male gentility penis, testicles ect. Thrusting, moaning, bouncing including vaginas are briefly seen, rape is discussed and people are accused, violence isn't constant but it does include blood and little gore character is stabbed, asthma attack soon leads to tripping cracks head open and hides body, brief sexual violence , 2 Choke scenes, Language is almost constant mild language and strong to including f*ck, c*nt, sh*t, c*ck and much more, no positive role models, one positive message which is most men should not cheat for it can have sad punishments but it still doesn't give anyone the right to kill, torture or hurt people
