Screenrant's 11 Trippiest Sci-Fi Movies of All Time

"While there are plenty of accessible sci-fi blockbusters, the genre is also home to some of the trippiest movies in cinema history. As a genre, sci-fi grants creators a unique level of freedom to get weird. The impossibly vast expanses of space, the endless possibilities of the future, and the tricky, reality-bending speculation involved in imagined scientific innovations all mean that the sci-fi genre is perfectly suited to stories that mess with the audience's minds. Even some of the best sci-fi movies of all time are psychedelic masterpieces that muddle the viewer's perception of reality, using the genre to bend and twist existential concepts like time and space in on themselves. Not every sci-fi movie takes advantage of the genre's propensity for bizarre storytelling, as the deluge of conventional space operas proves. There are plenty of trippy sci-fi movies that do offer viewers an unforgettably strange viewing experience in the process." - screenrant.com
