This is an uneven series in many ways: it starts off with a lot of action and then settles down into more of a thriller to fight corruption. I had the feeling that the writer went for the big surpise moments and then had to spend the next episodes trying to explain how the plot twists fit into place. It is also gory in places and you will have to suspend belief for some bits. That said it is a fun ride and Ahn Bo-Hyun is on great form as the prosecutor and also a good performance from Kim Woo-Seok. Not a must watch but if you need something to fill a few evenings and you don't mind blood and violence then give it a go.
