10. Battlefield Earth (IMDb: 2.5)

It’s the year 3000 A.D., and the Earth is lost to the alien race of Psychlos. Humanity is enslaved by these gold-thirsty tyrants, who are unaware that their ‘man-animals’ are about to ignite the rebellion of a lifetime, led by a resourceful human.
The film is unspeakably bad with no plot, terrible acting, gibberish dialogue, worst special effects, and poor costumes. Implausible elements like alien weaknesses, survival mechanisms, and human tech longevity overload suspension of belief. Hopeless devotion to source material results in ineptitude, stupidity, and poor budget use, leaving nothing worthwhile. Unintentional comedy from garbage scripting, technobabble, and ethnocentric themes turns it into a laughing stock, a massive mess of filmmaking failures.
