Timecrimes (2007)

Nacho Vigalondo transforms temporal circularity into an agonising trap of guilt, wherein an ordinary man becomes the unwitting architect of his own nightmare. Hector's frantic scrambles through the woods capture the horrifying realisation that every desperate intervention only tightens the causal noose. The film masterfully conveys how repetition strips away moral integrity, replacing empathy with panicked survival instincts.
