Jeremy Saulnier’s Blue Ruin (2013) is a stripped-down, atmospheric revenge thriller about a drifter who returns to his hometown to avenge his parents’ murder — only to spiral into violence and chaos. Blending realism and moral unease, it’s a modern American neo-noir and a haunting meditation on the futility of vengeance.
