Cert 15 Stars 2

There’s no need to stay up late for this plodding scare-free supernatural horror plagued by a demon who kills people in their sleep, and is based on the eyebrow raising premise over 40% of world’s population suffer from sleep paralysis, two thirds of whom describe being attacked by a demonic entity.

As the investigating criminal psychologist, former Bond girl Olga Kurylenko delivers a well-judged physical performance, but it’s not enough to compensate for the clunky predictable dialogue she’s saddled with, from a script which is so devoid of imagination and energy it could put Freddy Krueger to sleep.
