10 Sci-Fi Movies That Are Borderline Horror According to CBR

"The sci-fi genre frequently intersects with horror, particularly in stories that revolve around world-ending calamities that destroy humanity (and all our creations and discoveries). While many sci-fi movies contain heavy doses of fear-inducing elements, like 'Alien' (1979), 'Annihilation' (2018), and the 'Resident Evil' franchise, there are a few that verge on horror without completely giving in to jumpscares. In fact, it can be argued that these examples are more terrifying because they rely on an undefined atmosphere of cinematic dread to make their narrative points, one that viewers find it next to impossible to prepare themselves for." - cbr.com
