K2 is an ambitious independent drama. It started out with the introduction of a highly skilled mercenary ex-soldier, who looked like K-dramaworld's answer to Bond and Bourne. The drama then adapted the K-drama formula of melodrama, filler, flashback, love triangle and crying.

Story:
K2 is a mixed bag of espionage, political intrigue, romance, dysfunctional family and corruption in high circles.

Acting Cast 7,5
Chang Ji Wook and Song Yoon-A were exceptional in their roles.

Character assessment;
 K2 moved like lightning. He should be the executive trainer of NIS.
Choi Yoo Jin had excessive mood swings. She was bi-polar, psychotic, duplicitous, ruthless, manipulative, delusional. She should be the dictator of a country.
An Na;  bland! She should open a ramen shop.
Se Joon was a philanderer, dead beat father, sycophant. He should go on the talk show circuit.
Gwan Soo was the corrupt politician and K2's target. He should be attached to a bomb device.

Music: 7
The music kept the drama alive.

Rewatch value:  5
Some day!

Overall 6.5
The most annoying aspect of the production was the ridiculous abuse of Shaky Camera. The jerky movements caused the brain to readjust and lose concentration (especially when the international viewers were reading subtitles). This lowered the quality of the project, because it seemed as if amateurs were behind the camera, and in charge of the production.
