This film plays with the viewers memory, constantly taking twists and turns. Memento has two storylines that constantly play against each other, whilst the viewer is put to work figuring out which reality is true. We find out later in the film that the start of the film is actually the ending of our story, and where the protagonist is faced with an even harsher reality that it was his initial actions that were driving him in the first place.
The editing style of Memento is a refreshing take on how films ‘should’ work, taking an audience that is used to the linear structure of films, and possibly playing on this fact by completely scrambling the audiences perceptions of time inside the film.
