10 Forgotten Sci-Fi Horror Movies That You Need To Watch
9. Altered States
Some movies ruin their potential by being far too nonsensical and bizarre, but others absolutely thrive on how mind-bending and peculiar they are, with weird images and ideas galore. Altered States is one such example.
It follows a psychopathologist named Eddie Jessup as he experiments with drugs and sensory deprivation tanks to explore other states of consciousness. Naturally, as with most experiments in sci-fi horror movies, it ends up biting him in the back as he's dragged into a world of danger and mystery, putting himself and his families existence on the line.
The movie's biggest selling point, without a doubt, are the visuals, as the hallucinations are filled to the brim with creepiness, creativity and the feeling of being inside a fever dream. It's got some cracking 80s VFX that are impressive for the time but also dated in a way that makes them feel uncanny, making you feel like you're falling into a pit of madness yourself.
But, alongside the visuals, there is convincing chemistry between Eddie and his wife, which acts as the story's foundation, giving you a reason to keep going until the end.
