If you loved Communion, try Howling II: Stirba - Werewolf Bitch
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Philippe Mora, and they both carry the dread, late night mood tags, and they sit in Horror / Thriller territory. If that's the register that drew you to Communion, the second film will land in a comparable space — through a different lens.

What Howling II: Stirba - Werewolf Bitch is
Rustic Carpathians, full moon winter. A silver bracelet snaps in the snow. A brother tracks a cult leader through pocked VHS montages and fog-struck forests. A werewolf b-movie that slinks across crimson backlots.
