The Void (2016)

A local sheriff brings the victim of a mysterious attack to a rundown hospital, where sinister events ensue during a night of blood and gore …

Ambitious siege horror with all sorts of influences. After a disturbing opening scene, we have one moment of normality followed by a constantly twisting nightmare that never lets up. At one point it seems there’s a triple threat coming from different angles, and the story is at risk of collapsing from overload, but then the endgame comes into play through well produced set pieces and the climax brings some clarity.

The weakness is in the writing, which gives us two heroes, three pregnancies, over elaborate back stories, and plenty of shouty dialogue. The strength is in the effects and the photography and sound that create the hellish otherworld. The performances are OK, but the pace ebbs and flows instead of building steadily.
