Most of these movies are called psychological movies, but searching under this category I have not found anything that comes close to what I am looking for, movies like memento, 12 monkeys and primer are characterized by something, a person who knows information (Be good or bad), and is in a situation isolated from the rest of the population, no one other than the protagonist or a very small group of people knows what is happening and what it implies, that is the type of movies I am looking for, movies with isolated stories, if you know of any movie that makes you feel that I don't know what it is with the 3 movies I mentioned, please leave me the name and synopsis
I actually haven't seen those two you mentioned but I'm gonna take them as a recommendation.
I was also gonna mention The Wall (Die Wand) because it's a very lonely movie to the point of being bleak, and only the protagonist "knows" what's going on but it's not a man-on-a-mission type of narrative so I'm not sure if it fits the vibe. Also the pacing is kinda ponderous which I think suits the story well but it really doesn't have the same feel as a movie like Memento or The Machinist, which have a sort of urgency to them that The Wall lacks.
Ooh that sounds interesting, adding it to my to-watch list
