The core idea of a "purge" is interesting, but every single moment of "horror" or "thrill" in this film is a predictable jumpscare. It takes itself way too seriously and makes some heavy-handed social commentary, while at the same time being really unconvincing and riddled with tropes. Whenever one of the masked villains is on-screen you can count on them to silently tilt their head to the side, playfully skip with a weapon in hand, or giggle about killing. The main concept and Lena Headey's acting bumped the rating up a little.
