Momento Film Analysis

I have recently been introduced to the film Momento (2000). The movie features a previous insurance investigator who cannot build or maintain memories of his previous experiences.He begins to discover that his wife has been brutally murdered as it is the last memory embodied in his brain. As the movie progresses, one story line begins to proceed and develop as the other storyline retreats and reverses, unveiling different elements and events each time it occurs.
As a class we researched the genre classification of the movie and settled on a mystery/ film noir genre as it features codes and conventions of both genres, fitting it into the category. The essence of film noir aspects is evident throughout the entirety of the film as black and white effects are heavily used alongside dark and mystique, ambiguous characters. The black and white shots are mainly used in the past tense narrative of the film.  The protagonist of the film obtains a huge ambiguity as we as an audience understand his incentive to kill but on the other hand portrays a sense of justice and experiences frequent disorientation.
The movie also embodies a femefatale. This is a seductive female character that brings down the protagonist character. The ending of the film is very wide open for interpretation, also drawing the film further towards film noir.
The close of the film personally drew me to the narrative and story line to the rest of the film as I wished to make a conclusion on the storyline as a whole. Watching the film the second time around caused me to notice certain elements in the mis en scene which I did not notice the first time around and further shaped meaning as they were important to the narrative. This appealed to me because I appreciated the effort and time it took to create a narrative and structure of this quality into the film.
