Masterpiece of the 2010s, best Korean movie since Oldboy

Rating: 10/10 (2 January 2020)

Without my habbit watching all Korean movies an airline has to offer on bord entertainment I'd probably never heard of this movie, depending how deep its run in award season gonna be and I hope it goes deep.
The movie is captivating from the first second and shows quite quickly which morbid rabbit hole it's gonna go down and depending on your own character you like it at that point or you start hating like the 1% here on imdb...
everything else already got written, not getting the Academy Award for Best Foreign Movie will be the biggest snub ever. Period.
