Sauna - AKA Evil Rising (AJ Annila, 2008)

Interesting location in a Finnish swamp, set just after an interminable war between Sweden and Russia in the 1500s. The film is strong on atmosphere, there's an effective enigmatic approach to the supernatural, and several chilling touches (after the first time I saw The Innocents anything featuring bulrushes became unsettling). Echoes of the mighty Valhalla Rising here too, with its focus on a primal, indistinct, cosmic and supernormal presence. Its main strength as a horror film is that thing all too rare and difficult to create and maintain: enigma. Something timeless and quickly capable of rendering us insignificant, and it exists in the heart of the swamp - and yet you see nothing.

One of the lead actors, Ville Virtanen, also reminded me of a young Max Von Sydow, which is never a bad thing.
