I really liked this movie. It had some good and bad points.

The negative:
The intrigue is what ruined it a little for me. Not that it is not good, it really seems like the producers and screenwriters thought about it a lot. However, as the story progresses and we try to guess who is really the serpent, it gets really confusing. Towards the end, we do get some explanations, but some elements are still unclear.

The good:
Everything else was magnificent.

-The actors: The actors are so talented and beautiful! (And I mean all of them. From the main characters to the side characters). The acting just brings the story together. The chemistry between the couples was out of this world. The princess and Souyue may have had around 5 minutes of romantic screen time at the end, but they succeeded in making me fall in love with them and cry for their end. As for Boya and Qingming, the way of admitting their feelings in a such indirect way was truly beautiful and poignant.

The cinematography(image, fx, action,...): The whole movie is so pleasing on the eyes. The cinematography is just wow. The action scenes are really great too. It's really smooth and doesn't feel fake, like you already know it's CGI. The quality is just great. The decors also go so well with the interactions with the characters. As an example, the chambers of the Empress have that atmosphere of intimacy which makes the moments between the princess and Souyue more intimate and profound. The attention to details with the outfits of each characters is nice too.

The music: Amazing. It's been on repeat while writing this review.

Overall: I really recommend watching it. It's 2 hours, but you don't even realize it because the plot just has you captivated.
