Frontier(s) (2007)

Although at times Mr. Gens veers dangerously close to the unpardonable, with images that evoke the Holocaust too strongly, Frontier(s) finally works because its shivers are as plausible as they are outrageous.

Though neither subtle nor particularly original, Gens' spin on the meat-movie classic has both nightmarish energy to spare.

There's no depth, surprises, or wit to the screenplay, which seems motivated by the sole desire to generate the vilest, most disgusting people and images imaginable.

Can a movie be an adrenalin-fueled, blood-gushing thrill ride and still be as boring as dirt? Apparently. The French answer to "Hostel" and "Saw" -- Frontier(s) is a 100-minute hemorrhage that doesn't bring anything to the operating table of torture-porn but more gore, cruelty and misery.

As a satire of France's recent turn to the right, Frontier(s) is both hysterical and muddled; as straight-up splatter -- a Grand Guignol concerto of scalding steam, slashed tendons and table saw, with a solo for exploding head -- it's as relentless as it is hateful, hammily directed and derivative of the dreariest slop in contemporary American horror cinema.
