Un uomo chiamato dio (2010)

They're both k-drama action. If you liked this then you'll certainly like IRIS but I can't say it'll be the same vice-versa. They are both big budget productions but IRIS is certainly way better in its execution.

Both are about a son, avenging their parent/s.

Both are about revenge & love.

Both male leads have a hidden identity and are good at fighting. Both second leading males are obsessed with the female lead and want to hunt down the male lead.

A Man Called God isn't nearly as good as Fugitive: Plan B but they both contain very similar elements. The main characters both have a team working with them to accomplish their missions. If you liked A Man Called God you might like Fugitive: Plan B but not too sure that works vice-versa.

Both male protagonist have a cool demeanour, is fighting for something (a goal to reach). Both dramas have cool "agent" scenes and a female protagonist that fall in love with the male protagonist.

Both male leads at 'Healer' and 'A Man Called God' are badass with extraordinary skills. they both have a small team who helps them and the female lead is also a reporter. There is a need for revenge and lost relatives too. There is romance in 'A Man Called God', but it's mainly action while 'Healer' is more romantic.
