A very slow but increasingly unsettling Austrian horror/thriller called 'Hotel'.
Very, uh, 'hauntological'... A sense of creeping dread, eldritch folkloric evil lurking in the dark depths of the forest... with some Freudian undercurrents ('lady of the forest' ancient 'witch' martyr motif, the 'Devil's Cave' in which our heroine loses her presumed virginity to the apple-cheeked casanova of the village, etc.)
The acting seems ultra-germanic and stiff at first, until you realise it's *meant* to be that way- it only adds to the uncanniness of the atmosphere and the actors look a bit like puppets... The end inevitably, mercilessly creeping closer.
And the ending was in fact more scary (and beautiful) precisely because they didn't show you everything- Less is more.
And the interpretation can go either way (psychological, or at face value/horror story).
In fact, one can see this film as the antidote, polar opposite to VonTrier's recent gorefest: ...See this film instead! Subtlety is king.
(looks at post and realises she's written it in a very silly and pretentious style, but can't be arsed to edit that)
o) were very well judged.
