Let's start with what I didn't like:
1) Editing. From the voice over to the flow of the scenes to the episode duration, someone just either never got paid to do it, or just pressed the AI button and let 01 bits take their course.
2)Lack of chemistry. Two exceptionally beautiful people who fell in love bc it was in the script. Especially the FL, with the atrocious voice over, came out as emotionless.
3) The plot. The relationship btw the leads was more of a second thought than the main focus. Also, so many secondary characters that dominated so much screen time I had to speed watch half of the drama. Also, what's with the songs???Not everything has to be an in drama video clip, reminiscing of past scenes. Especially when the romance is lacking.
4) The fight scenes. Most of them incomplete, you only get the end result and that as an afterthought.
5) The villain(s). At first it's the ML, then you hate Shi Zu, then it's Sen Luo(who just dies more easily than expected), then it's the Evil Sect, then it's the Sword Sect Master to end with the Premier, what a mess, every 5 episodes you get a new villain introduced.
6) Why for the love of all chinese drama gurus out there the FL's paternity was never questioned? Is it such a taboo to ask "Who is your father?" Maybe he's the problem here and not every other Tom, Dick and Harry?
7) The ending. Inconsistent, unexplained just HE for the sake of it.

What I liked
1) The Dragon Lord
2) FL's mother's plot
3) Zhang Linghe. But I've yet to see him with a FL he's got chemistry with.
