Critic Reviews for Knock Knock
> Be cautious of the two slices of the free pizza delivered to your doorstep. Another flick that sets in an isolated place with the limited cast. A low budget film, which was a remake of the 'Death Game'. After playing a strong character in his previous film, Keanu Reeves is back exactly opposite to that one. Yep, remember what happened to the two men who break-in into his house in 'John Wick', but here it is like what if he's not able to handle them or to do anything about it kind of Circumstance. He played a normal family guy, a father of two children with a beautiful wife and a big house. The trailer itself revealed half of what the movie's. But the rest of the film is not bad at all, and that does not count as I'm praising it. The movie was average because of the writing was too loose. Not only predictable, but aimlessly moved and the motives were never explained. So the mystery remains mystery. It was one of those films that leaves behind us to suspect the possibilities. A broad open for a sequel, but likely there's very less chance for another film. The girls were so good looking and performed well. The theme aimed for erotic-crime-thriller, but did it achieved? I don't know, the original was released in the 70s, which might have been too sexy for that time, but in the present world, it is not that special or effective, just like 'I Spit on Your Grave'. You could watch it to enjoy your moment, but it would be a cinematically impressive with the great writings, actings, with twists and turns and all. 5/10
Just say no! Eli Roth directs and co-writes the screenplay with Nicolás López and Guillermo Amoedo. It stars Keanu Reeves, Lorenza Izzo and Ana de Armas. Music is by Manuel Riveiro and cinematography by Antonio Quercia. Reeves plays Evan, a devoted husband and father of two, who while he is left home alone, is visited by two young women soaked and apparently lost. Letting them in to his home as an act of kindness, things quickly spiral out of control. You do wonder if Eli Roth sits at home looking at the reaction to his movie and giggles like a schoolboy. It's invariably a distinctly average film, but it does get a reaction from the audience, something which Roth is gleefully aware of. Pic is actually a remake of Peter S. Traynor's 1977 movie, Death Game, which starred Sondra Locke and Colleeen Camp, both of whom lend their names to production for this release. At times it feels like we are part of one of Roth's wet dreams, or conversely one of his sick jokes. Yet as the cast struggle to instill acting gravitas (the girls actually become more annoying than frightening), and Roth chooses psychological themes over blood and guts, there's a deft whiff of a moral fable hanging in the air. While also of note is the nods to film noir, both in story and visuals. It isn't enough to save the piece, but it's interesting enough as an aside to the chaos inside the house. 5/10
**Finally, Roth gives us something of value: even with its flaws, this film entertains its audience and works nicely.** Many years ago, a film came out where a pair of young seductresses managed to sneak into the home of a middle-aged rich man, seduce him and torment him: “Death Game” is one of those films that almost no one will remember now. I haven't seen it yet, but having seen this modern remake, I'm curious to see the older film. Eli Roth gives us a very simple film. What I said above fits this film perfectly: Evan Webber is a conventional husband and family man who makes the mistake of giving shelter to two really attractive girls who, after a shower and clean clothes, decide to repay him with a night of adulterous and totally sinful sex. However, what seemed like an erotic dream come true turns into a nightmare when they begin to terrorize Evan. This is not a brilliant, surprising film, it will never join a pantheon of great films, whatever genre or subgenre it may be, but it works and gives us what it promises: a sense of menace and pleasant tension, entertainment and a decent story. Of course, there are problems. For example, how would those girls know so much about Evan and his family without having spent a good deal of time spying on him? They showed, at various times, that he had not been chosen at random and that there was an intention in what they were doing with him. This is weird because the movie wants to explain it, but it doesn't do it very well. Personally, I think it would have been better if the film didn't exploit their intentions and just played with all the information they could get from Evan on that short night visit. Be that as it may, this is, as far as I've seen, Eli Roth's best film to date: "Cabin Fever" was a decent effort, but very campy, and "Hostel" turned out to be simply unpalatable in its ambition to imitate the worst of “Saw”. Roth seems to have finally learned that what scares us most is what is beyond our sight or foresight. Liters of fake blood and human bodies being hacked to pieces only serve to ruin the theater popcorn vendor's business. Keany Reeves is the film's big star and the highest rated, and perhaps highest paid, actor here. He did a good job, with a character that, in other hands, could have been more limited, one-dimensional or sketchy. Over time, Reeves gives us a simple, down-to-earth, credibly authentic man, someone we can like. Someone who makes mistakes, but who still elicits sympathy by being punished far more severely than could be justified. Reeves never lets the character be just a puppet. However, the film is entirely dominated by female performances: slender and dangerous, Lorenza Izzo – the director's wife – and Cuban newcomer Ana de Armas deserve our full attention. Technically, it is a film that stands out for its simplicity: everything takes place in a unique environment, and the scenery and costumes are reduced to the simplest, but effective and functional. Cinematography does not bring surprises or innovations, it bets on conventional formats and solutions and on pragmatism. The soundtrack isn't especially notable either.
I get the movie. The movie is just not that good. It's pretty much a soft core bad porn movie.
