1. “The Invitation” (2015) – Dinner Parties Just Got Deadly
Ever been to a dinner party so awkward you wished you stayed home? Well, imagine that—but with cults.

This isn’t your typical “slash and scream” horror, but rather a masterclass in tension-building that escalates into pure chaos.
Why It’s Great:
- The performances are unnervingly believable.
- It’s a subtle dismantling of social norms—like “Guess Who’s Coming to Dinner,” but everyone’s insane.
- Perfect for anyone who thinks family reunions are scary enough.
