Kyoung-gu Sul is great. Nam-gil Kim is an over-moisterized non-entity. I didn't believe him as a cop or a serial killer.
Koreans love to make these "tricky" movies where things aren't what you think they are ... but giving a character Alzheimers shouldn't mean you get to make stuff up and go "Oops, I forgot" all the time. This film unravels from its own conceit.
