I finally got through all the episodes. Phew, almost dropped it a few times.

LIKES:
Beautiful sets and cinematography.
Special FX were good, same with CGI use.
Music was appropriate, but nothing stood out.
WRITING: The heavenly tribes aren’t as purely good as they seem. I liked that they showed the heavenly ones as being flawed. Also liked that the dark tribe/hell fire came across as stronger than the heavenly fire. Don’t see that often.
COSTUMES: Embroidery was nice, the dark/devil ML had a better costume than most.
ACTING: ML did very good and has matured as an actor. When they did the body switch parts, ML was good & FL did okay too. FL did best as the Goddess parts.

DISLIKES:
WRITING: Orchid Fairy (FL) is just too dumb and very whiney. It wasn’t like she’s just naive or innocent, more that she’s purely stupid. I found her ignorant too. (That all could be the actress’s fault or the directing, not sure which.) Typical tropes and cliches of this fantasy drama genre. Also the 2nd couple (Jie Li and Shang Que) wasn't necessary and the ending was disappointing. Also for all of the characters, other than Dongfang Qing Cang & his brother, there was no character growth.
PRODUCTION/EDITING: During flying moments or falling, it is so obvious that they are in harness with ropes.
FX: The swords all look like children’s halloween costume props. “Fight scenes” were very lame looking.
ACTING: FL was over the top cutesy and not in a good way. Some stand out performances, but the rest was just average. Even though ML & 2ML (Changheng) tried their best, there was just no chemistry with FL at all. FL (Orchid) had over the top cute fairy acting but just too much and got annoying fast. You can be sweet without a stupid voice, it was like a tooth ache eating cotton candy. Just terrible. From episode 12 and on I had to mute FL’s parts, because I just couldn’t take listening to her anymore. I read subtitles instead.
COSTUMES: The “crowns” or head gear looked laughably plastic. Not very creative in the costume department and if they hadn’t constantly told us she’s from the fairy realm, you wouldn’t know it. [Not by costumes, other than the pastel colours.]

OVERALL: So far very over rated, unless you are just starting out watching shows from this genre. As a starter Fantasy Drama I would recommend it, for those of us who have watched a lot of these types of dramas I don't recommend it (unless you are a child or a teenager). I watched it until the end, but was tempted to drop it often. Dylan Wang did a great job acting as Dongfang, enough for me to check out some of his other roles. (Originally I wasn't impressed but that was after watching Meteor Garden.) I'm glad this drama is over though.
