Knock Knock is the story of Evan Webber (Keanu Reeves). He's a loving father and husband who's staying home alone for the weekend to get some designing done while his family travels to the beach. Hoping to finish off the house he's working on, Evan makes himself comfortable, kicks on some tunes and gets to work, but not long after a storm breaks out, Evan gets a knock at the door. Two young women, Genesis (Lorenza Izzo) and Bel (Ana de Armas), come pleading for help. Evan lets them use his phone and dry themselves off, but it doesn't take long for them to seduce him, and what follows is not a lot of fun for poor Evan. Not a lot of fun at all.
Speaking of Roth, this is my first encounter with him as a director and I'm really not sure what to make of him. Perhaps this was just a bad first impression, or perhaps this is as good as he gets. With this film, he doesn't really do anything special. Everything he does has been done before and it's been done better. From his cinematography to the performances he's capable of getting out of his actors, everything's merely fine. Nothing more, nothing less. The low budget and limited locations could have done great things for this man's career, just like it did with M. Night Shyamalan earlier this year, but all he manages to do is make a film that gradually gets worse and worse and worse.
There are no stand out moments in this movie, either. In most bad horror movies, or even mediocre ones, there's always a stand out moment. Whether this is a good moment or a bad moment, that depends on the film. With Knock Knock, nothing in this film stands out. Everything is on the same level of forgettable, mostly thanks to the lacklustre performances. Nothing is convincing and no sequence springs to mind as being memorable. Even with disappointments like Annabelle or The Gallows, they had their stand out sequences. With Knock Knock, there's nothing.
