10 Great Sci-Fi Horror Movies (No One Ever Talks About)

Much like Kuso, Ken Russell’s insane bad trip Altered States is a film filled with imagery that most unsuspecting viewers will have trouble shaking.

As a genre unbound by the constraints of reality, sci-fi seems uniquely suited to The Devils director's command of hallucinatory images. But it took until 1980 for Russell to take full advantage of the genre's creative freedom with this unsettling, increasingly surreal tale of a scientist's doomed experimentation with psychoactive drugs and sensory deprivation.

Written by Network scribe Paddy Chayefsky, this one abandons the anti-establishment satire of both that 1976 success and Russell's own earlier efforts.

Thin on plot, the film follows William Hurt's psychopathologist, whose attempts to unearth the root of mental illness see his consciousness flooded with strange, surreal imagery during his trips, one of which eventually leads him to devolve into the missing link and finally a moving mass of pure primordial energy.

If that sounds strange it's because it is, and this film is filled with some seriously unforgettable imagery as the director attempts to visualize ideas too scary and mind blowing for many to even handle them in written form.
