Battlefield Earth is bad beyond belief. It's my favorite bad movie. There isn't even a close second including shitty b-movies. It's in a class by itself.

Battlefield Earth is a 2000 American science fiction film based on the 1982 novel by Scientology founder L. Ron Hubbard. It's set in the year 3000 and follows a human rebellion against the "Psychlos", a tyrannical alien species that has ruled Earth for a thousand years. John Travolta, who produced the film, stars as main antagonist Terl alongside Barry Pepper and Forest Whitaker.

Budget: $44 million

Battlefield Earth is like taking a bus trip with someone who has needed a bath for a long time. It's not merely bad; it's unpleasant in a hostile way ... I watched it in mounting gloom, realizing I was witnessing something historic, a film that for decades to come will be the punch line of jokes about bad movies.
