Knock Knock, Who's There? Crappy Movie. Crappy Movie Who?
5 November 2015 | by Matt_LaydenSee all my reviews

After the less than stellar box office return of Hostel Part II, Eli Roth blamed the internet and swore off making films for a long time. In fact, he hasn't directed another movie since then. He's produced, starred in and wrote a few, but never touched the camera again, except for the sniper film that plays in Inglorious Basterds and the Thanksgiving segment from Grindhouse. Almost ten years later and we have not one, but two feature films from Roth. The Green Inferno, which was actually completed in 2013, but held up until now, and the erotic horror thriller Knock Knock, which is a remake of 1977 film Death Game.

Did Roth coming back from "retirement" encourage me to see the film? Was it the deranged sexual element that would draw me in? No, it was Keanu Reeves my friend. Everything else didn't matter to me, I wanted to see Keanu Reeves in movies again. He did a kick ass job in John Wick, now I was going to see if he would be able to play a helpless cheat who is terrified for his life. A role that is really against type for him. Can Reeves pull it off? The man has been labeled emotionless in a lot of his film roles, so this would seem like it would require him to dig down and actually act. Now, he does manage to scream, freak out and indeed, act terrified at times, but there is always and I mean always, something off about his performances. Maybe it's his monotone voice or the deadness behind his eyes, but it doesn't always come off well. Don't get me wrong, I highly enjoy a lot of his work, but a great thespian the man is not. It looks like the man is trying here, I'm not too sure if he pulls it off too well.

Reeves plays Evan, an architect who has to stay at home for the long weekend and work, while his wife and two kids go to the beach house. One stormy night, he hears a knock at his door, two young beautiful women are stranded and need his help. While inside, they manage to seduce him, despite his constant resistance. The next morning he finds out that they won't leave, not without playing a game with him being an unwilling participant.

So the premise alone seems like a typical invasion torture horror flick, with the added element of sex and the intruders being young hot women. Once that is out of the way, the film offers nothing new or insightful. Roth, a man who knows a thing or two about the genre, tries to amp of the suspense a bit, but falls into the same generic traps all these films do. Knock Knock isn't sexy enough, nor terrifying enough. I guess it must just feel weird to direct your wife in a naked threesome with Keanu Reeves.

The question people will be asking themselves is, will Reeves live or die by the end of the film. I won't spoil how it ends, but the build up to that final situation is decent enough to make the film almost watchable. The denouement is completely wrong though and adds an unneeded comedic joke that is literally the very end of the film. You go through this long torturous journey with Reeves, only to have it end with a one liner? Really odd choice that left me scratching my head with disappointment. I wanted some kind of answer to what would happen next, but never got it. Roth leaves a little hint here or there, but I guess I wanted something a little more concrete.

What the film does accomplish is me, never opening my door to anyone. Not even two young, beautiful, wet women who beg me to let them inside so they can have sex with me. That's just for my dreams.
