There isn't a kind of media out there as utterly, unfathomably terrifying as cosmic horror. It's a subgenre founded on the fear of the unknown, with countless creators drawing from the core tenets developed by famous authors like H.P. Lovecraft to make truly unnerving stories. Yet despite how often people try to borrow its elements to create their scary features, they often fail to really understand what makes the medium unnerving — which is why fans are so lucky to have Aniara.
Directed by Pella Kågerman and Hugo Lilja, this science fiction film follows the inhabitants of a spaceship, thrown off-course from their destination and confronted with the growing reality that is their inevitable deaths in the cold darkness of space. Cosmic horror was built on stories of the impossible eternity that is the cosmos, with writers and filmmakers refining this concept into ideas that would drive the human mind completely mad. Too often, movies reduce this into a scary big space monster with a dash of science fiction tropes thrown in to appease a general audience. Aniara does the opposite; it uses the oblivion of space as its terror, and by utilizing that concept as its core monster, it helps viewers understand to a disturbing degree what makes cosmic horror so unnerving.

Highly recommend. Ran across this by chance and was completely enthralled.
