Alien/Aliens is a given for most people. I have been watching Event Horizon during the spooky season for years. What are some of your favorite books and movies with a horror/psychological thriller lean?
The first movie that came to mind is Aniara (2019). It's a great film that really goes beyond to show the hopelessness of being lost in space and how tiny we are in comparison. Fair warning though: This film will absolutely destroy you on an emotional level.
