IRIS drama is about a National Security System agent who attempts to take down a secret organization. After the introductory opening episodes, the missions are similar to what one would find in the American "24" series (excluding the "real time" element), with agents attempting to stop terrorist attacks with the use of satellites and information support technicians. Of course, this is in the Korean style with some romance and melodrama blended in. Acting is top notch, with Byung-hun Lee in the lead role and a very good supporting cast: Tae-hee Kim (his love interest and fellow agent), Seung-woo Kim (a North Korean agent) and So-yeon Kim (as the gorgeous North Korean sniper). Production values are slick, the scoring is great at times, and the pacing is very fast for a K-drama with plenty of shootouts (a few of which are fantastic) and suspense. Storyline is cliched but the secret organization is intriguing and represents a brilliant little twist on the North/South Korean conflict. Consequently, the relationships between the characters change significantly in exciting ways and the viewer will have an emotional investment in the protagonists. Highly addictive stuff. Production values are through the roof; various exotic locales, terrific cinematography, blazing gunfights and action scenes…they spared no expense here (for a TV series), and it definitely shows on screen. Two marines who are friends get recruited by the NSS (National Security System). While there, they meet the primary love interest who is their sub section chief responsible for training them. The 2 friends quickly take to their new jobs as secret agents, and are soon deployed in the field. The NSS is primarily engaged with dealing with their North Korean counterparts, but, it soon becomes apparent there is a shadow organization at work behind the scenes known as Iris…the goal of Iris is too pretty much pit the 2 Koreas (and other nations) against each other, so they can profit and rise to world power. After the botched mission by the 2 friends/leads, this show basically boils down to a matter of slowly uncovering what everybody's motives are, who's working for whom, who's ultimately good and who's ultimately evil, etc…Along the way, there's your main love interest storyline, the main friendship storyline, people being good and people being evil, characters reconciling with themselves and others over time in regards to what they believe is right and wrong, etc. This show is very entertaining and highly addictive. I would also like to note that I've always loved the fact that there seems to be no clear delineation between "movie star" and "TV actor" in Korean productions. Main actors and actresses go back and forth between the 2 mediums seemingly at will, and that makes for some terrific performances when you might be inclined to expect less since "you're just watching a television show". Highly watchable…whether it be for the typical melodrama & intrigue inherent to this Koren Television genre, or for the electrifying gun battles in the rush hour streets of downtown Seoul, or for the story & performances, or for just about anything and everywhere in between.
