Creepy, dark, intense.
Powerful acting by Lee Dong Wook. His signature cold stance combined with his method acting steals the light from Im Siwan.
Commendable cinematography, effectively creating cataclysmic reality, although too many smash cut IMO. Will keep you at the edge of your seat and compels the audience to ponder afterwards.
Would love a season 2 for the characters back story especially that of Moon Ju (Lee Dong Wook)
