I'm too disappointed to elaborate at length.
The show starts off REALLY strong - the opening map-retrieval arc is fantastic. The characters are cute and interesting, the acting's solid, the music's nice and there's loads of juicy wuxia action.
I can't say for what reason this great fortune turns sour, but my guess would be lack of funding and time?
Basically once we get past the martial tournament, it all goes to hell.
Actual plot progression is replaced by "convenient" melodrama, lots of angst and awful, just awful character development.
Characters who you grew to like turn out to be manipulative and terrible to their loved ones, "because duty".
Turns out the whole show's not about fun wuxia people doing a heist and falling in love. It's about stupid, annoyingly drawn out revenge ("justice") in a courtly intrigue type plot.
I HATE courtly intrigue plots. They suck ass.
The problem is that it's not even interesting as that. The drama is TOO LONG for its own good - towards the end there are like 5 episodes where things happen off screen and we're literally watching people talk in rooms. That's it.
The excellent and cool fights from the beginning? Gone. The fights are very few and far between, and they're terribly choreographed and performed.
The weak and predictable ending is just a rotten cherry on the entire pile of garbage.
Random notes:
- the actor of Ghost Boy nailed it. Menacing and had actual depth.
- the character of Shen Man Ching deserved a better show. She does NOTHING in the second half, just cry and get rescued.
- we get a few incredibly tame kisses and at least an implication characters had sex off screen. Wowiewowowow. That's something, I guess.

I was genuinely excited for this drama at first, but towards the end I had to fast forward through it.
