Image quality
Well I know this has been shot on Super 16mm film to cut costs by about 60%, but so has "Vera Drake", "The Hurt Locker", The Wrestler" and "Black Swan" and all these movies look way sharper and with better general image quality.
I am really distracted by the ridiculous amount of film grain. Like an ant colony crawling constantly over the screen. Did the filmmakers want to re-create a retro-documentary feel? I have seen a lot of documentaries and pseudo documentaries from the 70s, shot on regular 16mm (even less image area) - and they all look way better. What the heck went wrong????
