Run, don't walk, to see IRIS (now on NetFlix)
4 December 2016 | by canuckteachSee all my reviews

A stunning miniseries from South Korea about the 'NSS' (the South Korean Secret Service). Pardon me if I struggle with the character (or actor) names, but several performances are quite stunning. Character-development and -relationships are superb, irony occurs frequently, and there's plenty of action to match the slower sweet scenes showing the developing love-story between Choi Seung-Hee, the pretty female Service leader, and Kim Hyun-Jun, a stud recruit to the spy service. Talk about star-crossed lovers! They get separated, find each other, and then lose track of the existence of each other for months, but only after some very near connections. It's one of those: 'HEY! HEY! Look to your right - she's still alive... HEY! HEY.. Oh No..!' Unexpected sentimental stuff when you are are watching a cold-hearted spy & intrigue show.

IRIS also features a 'cross-over' character {that's a term I invented, by the way, so credit me if you use it!}: a character who switches sides, for some reason, to aid the protagonist. Example: the cowboy who breaks free from the wealthy townfolk in 'SHANE' and rides out to warn SHANE about the pending ambush. In IRIS, it's a pretty North Korean agent who falls out of favor with her bosses, and joins Hyun-Jun in his quest to get to the bottom of this IRIS conspiracy (after a few attempts to kill him, of course).

Also in the show is one of those super-assassin types, whose imminent presence is signaled by the camera focusing on his distinctive cowboy boots. Lots of fist-fights and shoot-em-ups to go with some well-staged car chases. Plenty of double-crosses and plot twists. It has everything U.S. network primetime action shows DON'T have. Like I said, run -- don't walk - to tune this thing in. I am writing this in early December: if you have down-time this month, add IRIS to the mini-series that will dominate your time, instead of clearing snow.
