It's a Spike Lee film!

Koreans only got thrillers done right in the 2010s. I generally dislike the clean(lifted from European arthouse) cinematography Park Chan-wook uses.

Only movies I really like from him is Decision to Leave and I'm A Cyborg, But That's OK.

You can easily observe how much PCW's style influenced kpop MVs and mainstream SoKor movies and you'll get what i mean lololol

If you want more thrillers from Asia, watch movies from Karthik Subbaraj(more Scorcese).
