This movie made me anxious, the whole thing, all the way through. A Hard Day, what an understatement. The main guy Go Geon Soo must have really ticked someone off in a previous life. I wasn’t five minutes in and I was shaking my head wondering how the hell he was going to get out of such a mess. The suspense in this film was off the charts. Most of the time I couldn’t tell what was going to happen next or how it was going to resolve itself. Why don't you give me a heart attack? I have to say I wasn’t impressed with the lead character. Played by Lee Sun Kyun, he’s an arrogant dirty cop who thinks he’s above everyone just because he’s a detective. He ends up doing things in desperation that a decent person wouldn’t even think of. Though it was interesting to see some of the ceremonial rites of Korean funerals, I found the funeral sequence especially appalling. Then the whole scenario changes as the story develops. I realized there could be someone worse as his nightmare escalates in an instant. The additional bump in Go Geon Soo’s life happens to be some mysterious crazy person. Go becomes involved in something bigger than anything he’s ever had to deal with and it’s an eye opener for him. It was a turning point for me because it shifted my focus and changed what I thought about the main character. There’s nothing like a psycho to change your perspective of things. Yeah, I felt bad for the poor loser. Eventually. The crazy psycho man is played by Cho Jin Woong. On the surface, he’s a calm and reasonable looking guy. He could be a sweet and caring neighbor for all anyone knows. However, underneath there’s this layer of a lunatic just bidding his time. As I watched his scenes I just waited for his switch to flip. I thought Cho did a great job of showing the multi-faceted personality as Detective Go’s adversary. What I liked most about this film was the constant change of events. Just when you think Detective Go can relax a little, the poor guy gets thrown another problem. If what happened to him didn’t kill him I thought the constant state of panic would have. This was a great suspense movie. There’s a lot of testosterone flying around. When the movie really intensifies it’s essentially two guys sparring and trying to outmaneuver each other. Who’s smarter? Who’s the step ahead? And for me it was who’s going to end the damn suspense!? The movie did a good job of navigating the story as it became more and more complicated. I was impressed with how each predicament played out. Despite his stress, Detective Go could be pretty clever.
