I started watching this show because my friend's circle hyped it up, they even mentioned about novel and bl aspect of the show. i had though time watching ep 1- 20 episodes, i pushed myself to not skip few episodes; once it past ep 20 i started to enjoy the show and looking forward for next one.

Cons:
1) CGI and lighting issues; even if your casual viewer, u will definitely notice the issues in scenes.
2) Music instruments syn, u can easily notice hand moments are not in syn with music playing in background.
3) Too much focus on some storylines than others. I personally didn't like the way they tried to white wash wei wuxian compare to novel/ anime.

Pros:
1) Plot : For 50 episodes series it really surprised me how their no one episode which felt like filler, every episode had its' purpose to add character development or story progression. It's thought provocative, how everything should not be taken at it's face value.
2) Acting by both leads, it took time for me to settle like 10 episodes but once i did, i was able to connect to their character. Even supporting characters like ghost general, Jin Guangyao really did well; few of them are lacking but we can see their effort.
3)Music, it soothing esp main ost as well entire album.
4) Main leads chemistry and relationship in series. Both production and acting teams had done extraordinary job in whatever extent they can within their set of boundaries to deliver romance part of the relationship and at times they walked on thin line.

At the end of day, i would recommend this series for others and even re-watch if time permits.
