I personally enjoy watching Ed Wood's classic flop, 'Plan Nine from Outer Space'. These movies are the type you have some friends over, order a couple of pizzas and have a few beers. For Battlefield Earth to be enjoyable it would take a pizza the size of Jupiter and more beer than has existed in the history of man. This film is not just bad not merely unpleasant, it assaults the senses. The story is set in the year 3000 and the unkempt aliens, the Psychlos, enslave the human race.
Humans live in a Neolithic style of a bad cave man movie.
They wonder about the sets as lost as the audience will soon feel. Among the major breaks with the reality of science is the fact that the electricity still works and the books that have been unused for a millennium are still readable. A Psychlo device that beams knowledge directly into his mind enhances his innate intelligence. Controling the planet are seasoned actors John Travolta and Forest Whitaker as Terl and Ker. Considering the gross makeup on these actors the studio could have saved a small fortune by hiring unknowns.
