The Omega Man gives an isolated survivor a city full of abandoned possessions and a routine that cannot entirely suppress loneliness. His opponents turn the pre-catastrophe world into an object of hatred, making technology both a survival resource and a symbol of what must be rejected. The film's central conflict is therefore ideological as well as physical. Watch how the apparently empty city changes once the survivor recognizes other people, and how possession of a treatment creates responsibilities beyond the defense of his own refuge.
