A Lot or a Little?
What you will—and won't—find in this movie.
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 & Scariness
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.

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.

Is It Any Good?
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.
Did we miss something on diversity?
Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
