For the first time, a young teenager learns that she is the latest recipient of a fatal curse that is passed from victim to victim via sexual intercourse.
It's a testament to how scary a movie It Follows is that for days after watching it, you walk around thinking up survival plans - should you hide, stay on the move forever, pass the haunting on to someone else?
It Follows is too uneven to fully recommend, but it does contain some of the most disturbing horror imagery. Far from the best horror movie of the year, it is still a vital reminder of how boundary-pushing American genre movies used to be.
