The Omega Man
This classic sets itself up as a last man on Earth drama, but within five minutes kills that premise. The baddies are a set of hippy-dippy night people who offer no real threat to the protagonist yet are trying to attack him for no real reason. Of course there are lots of other people who survived Armageddon. More hippies. We must increase our numbers so we can form an organic foods co-op! Heston is always great in these early seventies films, but, man, dumb movie.
