The complications and imperfections of Memento are shown through the editing order of the movie. The reverse order of the first scene, which is often undetected by first time viewers, resembles Leonard's memory fading. It gives the audience an unsettling feeling. Its a unique and difficult teqnique that prepares that audience of r the upcomming film and it creates a distrust of one's own psyche. The editing to the shots of the glasses and the gun give a sense of what happened without needing to show the gore of it. The lessening time between cuts intensifies the scene.
the order of the movie itself recreate the feelings Leonard has to go through living with his condition. it stimulates the brain like its a puzzle This is illustrated in the opening scene again. The undeveloping photograph is an undeveloping understanding of the film, and you have to go back to watch it at the beginning again to understand what the big picture of the film is again.
Memento has a bunch of possible realities. The scene to the right does that. Teddy talks to Lennard about what he knows to be true. He proposes the options that his wife survived and he was instead the one who killed her accidentally through insulin shots. Through the use of parallel flashbacks, the two stories are proposed as options. Either his wife had diabetes and needed insulin shots, or she didn't.
