The film has a very fundamental issue considering its foundation, which was based in basically reducing its entire diegesis to the long take gimmick and adapting its mise-en-scène to its form, and not the other way around, as it should be (unless you have a very ludic eye for conducting this game you are proposing). The already discussed artificiality that permeates the film despite its supposed interest for bazinian realism is obvious given that every camera movement is entirely manufactured, there is never anything in the film different from schematic composition of the screen for keeping its artifice going narratively and formally, and in this sense it’s very little more than a thematic park ride. I actually don’t have many problems with thematic park rides - in fact I quite like them - but when they are filled with awful drama, bad acting and utilitarian exposure rather than an actual construction of a world to amuse itself with, I have very little to extract from it. The film’s main issue is a very simple one: it aims at something that is extremely hard to achieve while working in a very limiting structure, and doesn’t manage to explore the potentials of this very limiting structure while attempting to do so, ending up losing the potential interest such an exercise might have entailed. It has its moments of fun, but they all get suffocated by the film’s failed efforts.
