The cinematography was pretty cool, with a old-school vibe in some parts. Some parts are VERY dark and quirky, so if you're into that kind of thing, you'll love it. If not, you might want to skip it :)
This movie can be interpreted in many ways, as it deals with themes of wealth disparity and the conflicts that arise from people earning different amounts of money. Ultimately, its meaning is shaped by each viewer's perspective.
Sure this movie isn’t “original” as it is based off of Naver webtoons Money Game and Pie Game by Bae Jin-soo, but what’s not based off something these days :P
