Ryoo trades his usual tough-as-nails image for that of a loser driven by desperation to take risks even if he gut instincts tell him not to; scenes of him groveling to save himself and Young-nam are disturbingly pitiful. As the chief, Lee possesses an evil glint that’s a bit of a giveaway that his wise and congenial manner may be a ruse; although his scenes with Ryu are highly charged, the actor’s rendering of duplicity and villainy is not exactly subtle. After his moving performance as a victim of male abuse in “Han Gong-ju,” Chun Woo-hee is again a bundles of nerves as a reluctant shaman, but doesn’t have more dimensions beyond that.
