I enjoyed S1 and had hoped the incomplete story of Ji-hyuk's past might have been expanded on, but sadly, whilst very lightly touched on, it wasn't at all.
I like the characters and Do-chang's sister was a much more pleasant person this time around.
Eun-hye has settled and whilst her past rears its unpleasant head, she is as mature and strong as ever. A very likeable girl.
The main story sees Ji-hyuk, Do-chang and the team once again struggling against a wealthy, powerful family (whose business is the backbone of the S.Korean economy), to put to rest a previously covered up shocking assault and latterly, murder. Of course, the family's influence is widespread ~ most will know what that means.
There are several other, quite unpleasant, murders that the team must also solve and similar to S1, they have to overcome attempts to apportion blame for unlinked events, to those perpetrators.
I actually preferred S1. I felt this time around the story was quite laboured and I lost interest and concentration on a few occasions. Usually, I would rewind to keep up with the plot, but tbh, that wasn't necessary for me with this and I don't believe I missed anything important; especially as I was still able to keep up with the storyline.
It isn't a bad watch and the casts' portrayal of their characters feels natural. The story, though, has been done before and I felt it was too similar to S1 in many ways, with nothing exceptional to match or add to it.
