Offers a gripping mix of sexual heat and nasty menace. It's "Dead Calm" meets "Very Bad Things," with English accents.

The film goes off the rails in the final third, sacrificing subtle character work at the altar of blood-and-guts survival horror. As mood-killers go, it's like a jab to the back of the neck.

Until it plunges into gore, the movie remains above the typical splatter 'n' scream fest. These careless hedonists are convincing, and the ensemble acting feels believable; the orgy looks very real. But the realism turns to caricature once the panicked party monsters begin viciously turning on one another.

A formulaic yet clever chiller that offers generous doses of sex and violence aboard a luxury yacht.

Shows the sort of edge in places that will be appreciated by horror fanboys of all ages, but is mostly too overwrought and over-the-top.

If Stanley Kubrick filmed an orgy like the one in this film, "Eyes Wide Shut" might have been halfway tolerable.

A female revenge movie. But you could just as easily characterize it as fairly well-executed exploitation.

It's got enough formulaic flair to make it a guilty-pleasure cousin of seaborne nailbiters "Knife in the Water" and "Dead Calm."

A thriller whose title remains printable only because the right people probably don't know that it refers to a violent sex act.

A workmanlike thriller that works as an (unconscious?) auto-critique of mainstreamed Internet-age hedonism.

Donkey Punch is almost humorless, and there's no wink and nudge behind the mayhem to absolve us of taking its ugly, class-obsessed subtext seriously.
