Despite the title, there is practically no tension in High Tension. The plot is standard slasher stuff, with two young women, Marie and Alexia (Cécile de France and Maïwenn le Besco), going on a trip to the latter’s remote farmland family home. During the night, a greasy, middle-aged killer (Philippe Nahon) comes and begins killing everybody. Whilst some of the film’s technical quality is admirable, with a suitable grittiness and ugliness, Alexandre Aja’s direction of the film is so inane and condescending towards the audience it’s impossible to take seriously, with foreshadowing that’s about as subtle as a tabloid headline. Even beyond this, any goodwill one might have towards High Tension completely dissipates on the reveal of the twist, a twist so idiotic that even M. Night Shyamalan would have blushed.
