In the sea of mommy-horror films, Run Rabbit Run would float somewhere in the middle. Despite Sarah Snook's imposing commitment to playing a mother haunted by her past, the story doesn't meet her halfway with a memorable script. The dynamic between mother and daughter gets stuck in an exhausting loop of sudden bursts of anger and angst followed by glaringly quick reconciliation. Twists and scares are present as Snook's character, also named Sarah, confronts the dark and disturbing truths of her past, but it feels more mandatory than useful. The potential for transforming gripping familial tension into horror is lost in a meandering mother/daughter fight.

Sarah Snook delivers a performance with enough emotion to almost mask Run Rabbit Run's thin plot. Paired with young Lily LaTorre, the two's chemistry is on an island of its own. Their dynamic occasionally suffers from their repetitive fights, but it still shines whenever they go head-to-head, decoding each other at every turn.
