A rather janky but on the whole, admirable effort with some nice melodramatic class tension.
Movement though was at once really basic and also dizzying and erratic with the camera swaying all over the joint, almost feeling detached from the rest of the body. It does admittedly get across the feeling or impression of climbing a tall building with ones bare hands even if it's not necessarily "realistic", though it did distract somewhat imo from the mood that the linear narrative was constructed to achieve.
