For me it is actually between 9.5 and a 10.

First, the choice of actors is amazing, it seems they were meant to do these roles. The fact that Luo Yun Xi used his own voice made a hell lot of a difference. His micro-expressions are phenomenal and he has portrayed all 4 characters effortlessly. You can actually feel subtle differences in his acting. Bai lu does justice to her role and was an apt choice. Their chemistry is so easy and effortless and amazing. However, the character build up of Li Susu is not as great as that of Tantai Jin.

Second, the CGI is point on! One of the best I have seen till date in Chinese dramas. you get hooked on to it and just do not feel like skipping. Kudos to the production team. They have done an excellent job in bringing everything together and have justified all production costs.

Third, the storyline moves fast in many areas, which is rare in Chinese dramas. So, that was a welcome change. The storyline does drag a bit between Ep 30-35, but picks up again.

I had just finished watching Love between Fairy and Devil and was not in a mood to watch another similar Chinese fantasy drama. But this got me hooked from Ep 1 mainly because of the par excellent acting of the main leads and the Visual FX.

I have already seen it three times and can watch again. Also, this one made Luo Yun Xi earn a lifelong fan!
