The movie tells the story of a night in the life of Evan Webber (Reeves), a husband, father of two, and accomplished architect, that, staying alone for the weekend, suddenly has, at a certain rainy night, two girls knocking on his door, telling him that they got lost, while looking for the address of a party. Soaked by the rain, and virtually lost, Evan wants to help them both, and let the girls enter his house, but this will turn out as the biggest mistake of his life.
While the premise of the movie is really interesting, the movie becomes progressively tedious, tenaciously dull and inherently obvious, especially when it comes to the girls, as the movie progresses, that reveals themselves to be just two bored females, looking for fun at the cost of easily seducing middle aged and successful married men, just for the sake of playing a psychotic game.
As the story unfolds, the movie becomes more and more pointless and seemingly random, especially when, towards the end, nothing unusual or really clever happens, and the plot follows just another conventional linear narrative arc, with a simpleton objective, with nothing more to offer, being a great disappointment, after all, creating expectations that not fulfill the audience, in any way.
Another severe problem in the movie is Keanu Reeves choice for the main role. He is not convincing as a husband and a father. Perhaps for the reason that we do not see him take this kind of role frequently (never, so to speak), and perhaps for the fact that he has not taken – ever – neither roles in real life. For these reasons, it is quite hard to see him in this kind of role, and his acting simply doesn’t buy credibility – “chocolate with sprinkles” – nor it is convincing enough, to help us believe his character. It turns out to be comic – and voraciously funny – at certain parts.
Eli Roth is a great director, that is for sure. While this movie will not damage his reputation, will bring nothing to it, either, absolutely. Unfortunately, Knock Knock turns out to be a great sum of talents, wasted in a worthless filmmaking effort. Knock Knock, in a best case scenario, deserves one and a half star for its score, at the most possible optimistic evaluation.
