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 had forgotten to mention donnie darko)
I had mentioned 12 monkeys and primer because it has a similar style to memento despite having different environment, one that I forgot to mention was donnie darko, these movies have an unconventional narrative and endings, these characters are in a much bigger situation than they can measure, but for those who were not involved that never happened, since they never saw what happened from start to finish, when one of these movies ends, you know that it was not a happy, sad or neutral ending, which what happened there was something else
