While watching you can tell this was made by a film director. The cinematography is great, the fight scenes were awesome, the close up shots on Heo Joon Ho and the cop turned loan shark were fantastic. Now that I've used up all my adjectives, the weakness of this show is the plot. It seems to have a flow for 6 episodes then turns into a new show, almost a season 2 in episode 7 and 8. Understandably it is because they needed to edit around the lead actress, but if you don't know what happened you find a choppy plot.

The brotherhood between Woo Do Hwan and Lee Sang Yi was the best part of this series. I found myself wondering why directors haven't used that cute side of Do Hwan up to now. He's this big muscly man who can kill you with such gentleness in his eyes. The first introduction of his character sets the tone for how he acts and thinks towards the whole series. Sang Yi is a bit underused, he's comic relief and a screen partner that brings out Do Hwan's cuteness but we end up knowing nothing about him other than he is really loyal.

Heo Joon Ho and Park Sung Woong bring their A game as always. The former has always scared me since Come and Hug Me and in his one fight scene I thought he would win. Here the director understands that his strength is in his eyes and enhances that with every person he has a scene with. If I was watching PSW for the first time I would have hated him but I've seen him in roles where he's nice so that softened him for me. His ending was a bit anti climatic though but man, I have to hand it to him, he's doing those stunts at 50.

Finally, they really could have done without that chaebol subplot and given more to the boys. The most interesting bit for Gun Woo's development was when he asks if he's really become a bloodhound. The chaebol did nothing but whine and whinge the whole time he was on screen. He didn't deserve a bit of Gun Woo's kindness, and that while charity bit at the end was laughable.

TL;DR This show had potential but it drops the ball in the last stretch
