I have read the novel this movie was based on and one thing is for sure: I HATE how they adapted it.

The only good thing I can say say is that Wang Kai was okay! He definitely got part of the essence of Prof. Yukawa (his original name in the novel). Shi Hong unfortunately did not live to my expectation of his novel counterpart, and I absolutely disliked the extreme woodenness of his character and illogical decision making. How they established Shi Hong and Chen Jing's relationship was also not as well shown as it was in the novel as well. They cut out some great parts from the book, and added things for dramatic purpose which was COMPLETELY UNNECESSARY to me.

BOTTOM LINE: PLEASE READ THE BOOK. It is so much better.

PS: I might edit this review when I watch its other adaptations.
