High Tension is one of those slasher horror films that actually isn't cheesy. This movie actually has a very suspicious and mind bending storyline and plot which near the end of the movie, it has a shocking discovery which reveals the real killer and their true intentions. The violence in this movie is very realistic and extremely graphic in which is committed by a mysterious man armed with a razor, which he uses to brutally murder his victims. One man has his face slashed when he opens his front door, and screams in pain, which you see the bloody slash wound clearly on his face. The killer puts his head between the staircase and shoves a drawer to his head, which you see his head graphically tear off. A woman tries to hide from the killer, and she sees another woman hiding in the closet. The killer grabs the woman and graphicaly slits her throat wide open with a razor. You see the wound clearly gape open and blood gushes out, and she falls to the floor gasping for air. The killer uses the razor to cut off her hands in order to keep her from calling the police. The woman dies shortly afterwards. A cashier at a gas station is busy stocking products until the killer swings an axe towards the man and it thrusts through his chest. You hear gross crunching and gurgling sounds from the bones breaking. Very graphic and bloody. The killer masterbates with a woman's severed head and you briefly see him climaxing in the woman's mouth. He finishes by throwing the woman's head out the car window. Very disturbing and sickening. Language can be strong and vulgar, but infrequent. Uses of f**k, sh*t, d*mn, and several sex terms. There's no sex in this film, except for the decapitated head bj and scenes of one woman masturbating in her bed with her hands down her pants with graphic thrusting movement and heavy breathing. In the beginning, it shows a woman seeing her best friend and her parents in a beautiful house out in the country, until when the killer breaks, that's when the tone and atmosphere of the movie becomes extremely tense, dark and frightening. Even adults will find the deaths in this movie very disturbing and gruseome.
