Honestly, it's very hard to review this drama because the opinions are very clear-cut: either we loved it, or we liked it a little, or we absolutely hated it.
Personally, I went through all these opinions while watching this drama.

I hated it:
- From the middle to the end of the story. It doesn't make sense anymore, we could finish the drama at episode 12
- The acting of the main actress, which sometimes is really bad. However, we see a real evolution of her acting in the drama. She is good at the end hm.
- The 15 min rewinds before each episode.

I loved it:
- The main actor is really excellent. I really didn't think he was great at the beginning but he is just made for this job and this role.
- The beginning of the story : I think the main plot is really good but the explanations are too bad.
- The fact that sometimes I was surprised and/or sad: some scenes really gave me chills etc.
- The FX but woooooooooow. The work of the artists is impressive!

Basically I wanted to put 5 but in truth I still had a good time and not listening to other reviews, this note is personal and only based on my feeling! The drama itself is not worth 7. I would not watch it again but I still wanted to finish this drama.
