The Telegraph by Robbie Collin

Mandy exists in its own supremely unnerving horror dimension.

The Playlist by Russ Fischer

Through Cage, the film’s straightforward revenge plot becomes a King Crimson album played at half speed and twice normal volume; a bizarre and bloody outing with a strong heart beneath the surface.

[A] hypnotic midnight movie, which veers from astonishing, expressionistic exchanges to gory mayhem without an iota of compromise.

Most surprising of all, Mandy isn’t solely about the carnage-heavy path for revenge. Cosmatos knows that the impact will be much greater felt if there’s an emotional backbone. Thus, one can feel the soul-churning passion behind every popping eye and crushed skull.

Either you are one of the devoted or you’re not. You won’t know what camp you’re in until you see it.

A sensuous swath of striking imagery and otherworldly atmosphere, Mandy is a hypnotic, bloody pleasure.

The Hollywood Reporter by John DeFore

Cosmatos' ability to put us in Red's head — overwhelmed at first with pain and fury, then saturated by the strange drugs he for some reason feels compelled to try — make this much more than the usual exercise in vicarious bloodshed.

It’s a fetish object, a juvenile art-installation stunt. It panders wildly, but also skillfully and effectively, to its demographic—and you probably know if you belong to it.
