This title's translation is "green night", and the movie is the essence of the dark side of the color green.

🔸️You should watch it at least for the incredible camerawork. The camera is always static but the composition and the colors contribute to the depressing viscous atmosphere while nothing seemingly unusual is in the frame. This is the director Yoon Seo Jin's debut feature, and, while it's not a masterpiece, the directing style is intriguing enough for me to wait for his next movie. It's dark. Someone's death follows another death, and all in the scale of one family. The main issue would probably be the short premises that don't develop into the full genre or subplot.
