Reminds me of Werewolf
When watching this noticed that the style of filming used in a lot of this movie is very similar to what was carried out in many episodes the TV series "Werewolf"
Yet I can find no connection with any of the directors/producers etc.
Slow motion techniques, slow pans, 80's synth style background music, very dark and mysterious style of filming, slow progress before anything much happens.
Love it.
