If you are familiar with the Chinese Xianxia/Wuxia genre (dudes with long hair and swords, females with elegant gowns and beautiful headpieces, magic, sects, demons etc), then this is one to skip. As someone who has watched more than my fair share and read so many books in this genre, I can say it's very, very disappointing.

I had high hopes before this aired. And when it did, I was ecstatic and manage to binge the first 8 initial release episodes as I usually do. The beginning is like any other beginning of this show type. Nothing extravagant, but it was good. But starting from the 20th episode or so, things started to roll downhill. Characters seem to come and go, plot points seem to vanish into the void and appear out of some other dimension, and our leads seem to have more mood and allegiance changes than a 13 year old girl. I ended up dropping it and only recently picked it back up and finished it.

Story: ^^^ I think that was a decent explanation of what I thought

Acting and cast: The leads didn't have much material to work with, so nothing impressive, but the acting definitely wasn't bad. One thing though, the leads have basically no chemistry, or the script didn't manage to let the actors convey their emotions properly. Other than the leads, everyone is basically forgettable, except for the old master of the ML. I quite like that dude.

Music: Forgettable.

Rewatch Value: Probably not unless I'm desperate.

Overall it's just... weird and weak. Weird and weak pacing. Weird and weak motivations. Weird and weak chemistry. Weird and weak characters. Weird and weak plot. It had potential, but the show simply couldn't use it.
If you haven't seen much if this genre though, try it. You might have a better opinion of the show. If you are frequent viewer of this genre though, move on and watch something better.
