Eraserhead (1977)

A film that defies conventional logic and storytelling, fueled by its dark nightmarish atmosphere and compellingly disturbing visuals. Henry Spencer is a hapless factory worker on his vacation when he finds out he's the father of a hideously deformed baby. He moves in with his unhappy malcontent girlfriend, and the new parents are nearly driven to insanity by the child crying endlessly, day and night.
