It's documentary week over at Netflix — unofficially, I might add, but with the start of a two-month season of documentary films and several other high-profile non-fiction releases, it's a great time to catch up on events in the real world.

Mercy For None is an intense action thriller headlined by So Ji-seob, Huh Joon-ho, and Ahn Kil-kang. The story centres around a former gangster, who re-enters the world of the underworld to unravel his younger brother's mysterious death.
