"The insinuation of camera movements and the familiarity of the same forms recurring in black and then luminous white shapes, makes X an intriguing visual play on positive/negative space. Scale, depth and angle of view are indecipherable. Is it the object or the cameras which moves across the frame? This Rubic's cube for seeing simultaneously demonstrates the illusionism of cinematic space and the camera's ability to isolate and transform. Grenier's use of silence in X is perfectly à propos to its concerns. -Raphael Bendahan, Vanguard, Summer 1985. Preserved by the Academy Film Archive in 2014.
