In my opinion this is a misunderstood film.The simplicity of the writing allows room for more creative content and focus to lay in other aspects such as, editing, sound design,lighting and framing. This is a conscious choice made by McVicar and it is evident in how he chooses to structure the film. The writing is pretty straightforward and not unique but other elements are cultivated and focused on greatly like the editing, framing, lighting and sound design. Just because there is no explicit dialogue to establish the story, it doesn't mean that the audience lacks information. I think the rating is a bit harsh. Sure you need to pay more attention than a mainstream popular culture film, but the movie gives you a pretty good understanding of what's happening without dialogue and that is much more special and futuristic than your average dumbed down movie.
