This movie simply isn't worth that much thought. Battlefield Earth is junk, not even enjoyable junk. The plot is jumbled and poorly edited, the dialogue laughable, and special effects seldom appear so common. A performance by John Travolta in which he abandons everything that ever made him cool is the rotten cherry on top. This sagging saga is set in the year 3000 when an alien invasion has turned Earth into a wasteland.
Humans are back to wearing fur, and braids are still a popular coiffure.
Jonnie's bravest act is keeping a straight face while cheesy light beams pump knowledge into his noggin. A few extra hours skimming amazingly preserved books in the Library of Congress make him Einstein-like. Jonnie gives remedial lessons to his grunting co-conspirators. Nevertheless, the connections between Battlefield Earth and Scientology are worth noting. Apparently, transportation is no problem when nothing else works on Earth.
