It’s hard not to wonder who will take care of these kids now that things have fallen apart. That line appears in the novel, though it's missing from the film adaptation. I enjoyed David Brin’s story about settlements arising after a disaster and the character known as "Gordon Krantz." My initial viewing of the lengthy movie left me feeling let down; it seemed like the theme of responsibility had been disregarded. Still, this narrative about someone who twists Shakespeare grew on me over time. David Brin himself stood by the film, asserting that the ending to the conflict between the Holnist/Survivalists and the postal workers was well-executed. The itinerant protagonist, traveling with a mule, performs a distorted version of Shakespeare for food and shelter in various settlements. The situation quickly deteriorates when a Survivalist force encircles a town and forces men and boys into their "Army of the Eight." The leader of this group insists on being the only educated individual around and attempts to eliminate “Shakespeare” after having the traveler’s mule cooked for dinner. Following a close call, the drifter discovers a U.S. Postal Service vehicle containing a uniformed skeleton and a mailbag. This marks the start of his next scheme: posing as a mail carrier—which evolves into a mission led by "Ford Lincoln Mercury," his new postal colleague. A romantic subplot emerges when he is asked to sire a child for someone who contracted a severe case of measles. The Holnists reappear, and the pair escapes from the settlement. Following a harsh winter, the drifter and the pregnant woman return to liberate the village from the Holnists, who have been targeting mail carriers. A final confrontation with an "ineffective former photocopier salesman" results in “The Restored United States of America” and a monumental statue honoring The Postman. It earns 7 out of 10; however, the book deserves a perfect score of 10/10!
