“IT” opens with the cold dusty den of Bill’s bedroom. The rain is pouring and while the town of Derry seeks refuge, there’s an ominous atmosphere right from the outset that there’s something lurking in the edges of this warm and cosy world. Julie Ducournau’s “Raw” begins on a quaint deserted country road, framing the sporadic passing traffic from a position on the side of the road where you’d imagine a speed camera to be lurking. A car comes into frame, and just as it reaches the centre, something suddenly darts into the centre of the road. The car swerves and crashes hard into a tree, killing the occupants. This was clearly no accident.
