“The Gangster, The Cop, The Devil” (악인전)

“The Gangster, The Cop, The Devil” is not a good film, but it’s watchable because its star is Ma Dong-seok. The burly actor stars as a mob boss whose street credibility takes a beating when he is nearly killed by a floppy-haired serial killer (Kim Sung-kyu) — whose modus operandi is rear-ending drivers and then savagely stabbing them to death.
