One take shot been popular in recent years. Hill house ep5, a japan zombie movie did a great job but definitely not this one. Just 4 people interacting in an apartment and no difficulties filming in this movie at all. Storyline turn me down the most. I understand it try to make a scene but sooooo ridiculous. The black white coloring cuz poor lighting as one camera man, no lighting man. Rate 3 as the one take shot and no big mistake I seen. One second maybe a actor mistakenly look at the camera man.
