i am a big fan of this MDZS and many other c novels, and after watching guardian( a sad fact is that i never finished this one ) i really hated the fact that this is also going to be a live action.Its not that i wanted it to be a show with BL scenes (which i think is just some wishful thinking while looking at current censorship issues) but the thought of getting something which is totally different from original story line was just depressing . so, i completely ignored it until it started to show on my YT recommendations .
I almost didn't watch it. Though now i am glad i did.I was astonished to see all the characters so close to originals . The acting i think was great and so was MUSIC which i think it indispensable part of the story.
As far as novel adaptions are concerned no matter what genre this one is my absolutely favorite c drama. I must say that this is an absolute win for book lovers who actually wanted to see it getting adapted to a great drama. This drama is the fine example to show how adaptations should be done without compromising the original.

To conclude i would say that it is a must watch show for anyone who actually love watching good dramas ^^
The only reason i gave re watch value 9.0 is because i know how much time one has to sacrifice to watch a show with 50 episodes :D
