The plot was beautifully written and the acting was superb. The CGI was gorgeous and the set was amazing.

I'm knocking points down because the pacing of the entire show was slow. I understand that with all the intricacies, every arc was needed, but the decision to slow down some of the scenes were unnecessary. The dramatic scenes felt very "bollywood-esque" with their multiple angles of the same scenes/facial expression. Some of the fighting scenes were also unnecessarily long.
The constant misunderstandings got tiring halfway through the show. Ye Xiwu, as understanding and trusting as she was, didn't trust enough and that was a big character flaw that was never mentioned. While there was a big focus on his undying love for her, it didn't really make sense since she wasn't very sincere to him during their human arc. It was implied that she loved him when the fox demon would tease her, but her actions didn't really proved it other than she didn't kill him right away, and treated him with some kindness because she wanted him to not be evil right away. Everything she did fit with her missions' agenda rather than her own heart.

Also, Luo Yixun and Bai Lu definitely carried the shows, the side actors didn't convince me.

Also the blood was an overkill. And no one got their happy ending. The reason why he chose to save the world was because despite all the miseries, there was the good times that are worth cherishing and saving... EXCEPT the entire series was just tragic and sad and full of betrayal. Literally no one got a happy ending.
