I think that if there are specific elements that have to focused upon in your film study, these have to be represented in your work. Outside of these, I believe that one element that can be used is the use of camera work and cinematography in the film. One of the most challenging elements of the film is that the one has to feel a sense of empathy about Chris and his predicament. Such an element is not difficult, in general. However, there is a challenge in making the viewer fully feel the physical, emotional, and psychological strain that his predicament brings out in both he and his son. I think that the use of closeups and camera shots help to bring this out. In the moment when Chris is talking to his son about what it takes to be successful in life as he is leaning against a fence, there is a cinematic technique of the close up camera angle that enables the viewer to be immersed in "the moment." I would say that a film study that focuses on the cinematography in the film as well as how it harkens back to the classical Hollywood idea of being able to use "the moment" as a way to bring the viewer into the film as opposed to merely watching it could serve as a strong film study.
