First, the GOOD STUFF: This Kdrama has about a zillion plot twists throughout the show and you have to really pay attention or you may miss something very important. The writer does a great job of giving you tiny bits of information until they are ready to lay everything out for you.

The actors and actresses do a great job in this series. Every character is unique and interesting and important in their own way. There are a lot of actors/actresses in the show who are only in the series for a short time, but are important characters, so that is an interesting part of the story as well.

The NOT SO GOOD STUFF: This show is super violent so if that is not something you can handle, I'd give this show a pass. It's not violent all the time, but when it is...it's brutal. Also, I was not a fan of the ending. I found it confusing and frustrating. Others may not feel that way and I sort of get when the writer was trying to do, but for me...it just didn't work.

If you like a slow burning mystery, you might enjoy this show, but just be forewarned about what I mentioned above.
