Toni Collette delivers a powerhouse performance as a woman grappling with grief, rage and guilt as her dysfunctional family falls apart in this unsettling horror chiller.

Collette is an artist who crafts precise miniature dioramas, including scale models of rooms in the home she shares with her subdued husband (Gabriel Byrne), pothead teenage son (Alex Wolff) and misfit 13-year-old daughter (Milly Shapiro, embodying possibly the creepiest child since Damien in The Omen).

This is a little bit unnerving by itself, but nothing compared to the uncanny goings-on that follow in the wake of Collette’s unloved mother’s death.

Be warned, this slow-burn film, superbly handled by writer-director Ari Aster, is seriously spooky. Expect prickling terror rather than jump-out-of-the-seat scares, although there is one sudden shock to make you gulp.
