I have never written a review before, but I just feel like I have to write what's on my mind.

This drama, whilst deciding whether to watch it or not, I thought this was not going to be my cup of tea, I told myself If i didn't like it by the end of episode 1 then I'd drop it. I've been in a drama slump and I could not finish a single drama.
Not only does this drama have kick ass characters, but also strong women (which is a breath of fresh air from the regular damsel in distress trope). The plot was intriguing, satisfying and heart pounding. I was so immersed in the actors acting I felt like this was real..
Can I just say I wasn't really a massive fan of Lee Joon Gi, but oh my god I am so angry at myself for not watching this sooner. His acting made this drama worth the while, i love the vigilante trope, I love how he is so charismatic and so diligent when he needs to be. His expressions, his martial arts, you can tell he worked really hard for this drama, and it paid off.

I'm 100% recommending this to everyone I know who watches Kdramas.
