Knock Knock has something genuine to say, and it uses some really dark dramatic beats to get there.

Roth and Reeves locks us in for an increasingly terrifying thrillride.

[A] glossy and reasonably fun update of Peter Traynor’s 1977 exploitation movie “Death Game.”

The best villains are those whose motivations prove uncomfortably persuasive, and Knock Knock's drop-dead-gorgeous home invaders predicate their cruel game on too shaky a foundation to truly unsettle.

Little here is going to challenge the opinion of Roth as a bratty provocateur, but it’s still fun to experience a latter-day thriller pushing so many buttons in broadly the right order: if Knock Knock’s no more than a sick joke, it’s been very shrewdly constructed.

The movie's uneven tone and ridiculous twists never quite gel, but Knock, Knock is so eager to please that it's hard not roll with the absurd depravity on display — which has been the essence of Roth's appeal from the outset.

A film that flirts and flirts with explanations for its action without ever delivering.

Young actresses, Lorenza Izzo, who plays the dark-haired vicious vamp, and Ana de Armas, a Marilyn Monroe-like nymphette, are fine as the sociopathic femme fatales, toying with their sexiness like a loaded weapon. But Reeves is the obvious big draw here, and he’s fun to watch, alternating between exasperation, fury and helplessness.

Because it’s written and directed by slick slasher king Eli Roth (Cabin Fever, Hostel), expect some genuine, well-executed thrills that keep the adrenaline going. This is a good thing, because Keanu Reeves has the adrenaline rush of road kill.

Knock Knock is a nasty bit of business, and fans of Roth are not likely to be disappointed. But for everyone else, the joke's on them.
