Movie is qualitatively one of the worst ones I have watched, but I don't hate it. Also, surprisingly, I don't regret watching it. I went in knowing absolutely nothing about the story.

First of all, horrible, horrible writing and editing. The way the story is told is very choppy and jumpy, and it feels like you need to know about the story before watching it. Even if I knew about the story though, the way the scenes are put together and the way they end so abruptly...terrible. The first half was difficult to get through, and I took a pause.

I think the second half is more watchable because there is more action. The movie gets better after that fight with the monster. Also, as the backstory is revealed (albeit still in very choppy ways), the leads develop chemistry-ish. I think I was able to convince myself through sheer willpower and the pretty.

CG is okay since I've seen worse. Everything is very bright colored and fairy tale-esque. I may have seen some of the worst costumes and makeup ever in a production in this movie though lol

Oh, but wtf was the ending? Was there supposed to be a second movie? Also, what was up with the frozen master guy?

Overall, consider watching if you are fan of the leads (not a must) and may be curious about the drama.

Is it worth watching for Yang Yang? I think it was for me.
Does he cry very prettily? Yes.
Has he improved since Love O2O? I think he has a bit in here. He goes from robot to robot that cries pretty.
Bonus: great kiss scenes (rewatch just for those)

If anything, this movie has got me interested in trying out the drama. (Looks wise I prefer Yang Yang, but the drama version definitely has the better actors. Also, this story is more suited for longer format production - drama or multiple movies.)
