Some many twists and turns. Don't blink and don't turn your head. Jung Jae Young as the tortured Lt Choi and Park Shi Hoo as Doo Suk were excellent. The supporting cast also did a great job in reeling you into the story. The action sequences like the car chase, the alley chase as well as the ending scenes were well done and choreographed. Like I said, don't turn your head or fast forward because you will miss some serious details. Park Shi Hoo should do more action. His scene in the elevator was great to watch. Here's hoping for a comeback in the movies. Still can't wrap around my head people saying this was boring! Never a dull moment to me. But be warned, this is NOT a romance!!
