If the story doesn't explain much, then the problem is with the story. The story has to be complete on the subjective level (emotional resolution) even if the objective level (visual story) has some dangling pieces. It could lead to a sequel but the movie feels "whole and entire" as it is. "Watchmen" is an example where the story develops but the heroes lose because the events leading up to it had been planned out in advance by the antihero. The reveal is the resolution.its a thriller that I have trouble getting all the sttory elements right ... It was meant to be a movie that starts and doesent stop to explain much since there is not enough time, since the villain is 15 steps ahead of the heroes.
