ok i just saw the wailing (2016) and heres my review:

pretty good, a little too long, but still satisfyingly spooky. unfortunately the main character is a cop (boo) but its still pretty good regardless. if youre into like demons and a mixing of like modern society with witchy/shamanistic aesthetics then youll probably be into it. pretty classic korean horror film uh 8/10 interesting but couldve been shorter imo
