Unbelieveable. That's the only word to describe this whole drama. I watched some best drama, But this one is very crazy.
Story : The storyline is very good and has many plot twist in it. Initial Episode (16 years later) indeed made time confused, and also episodes 10-20 was a little bit boring. But what happened next really covered all the flaws in the previous. Complaints above can also be overcome when you watch The Untamed Special Edition (cut version to 20 episodes).
Acting : As a beginner at C-Drama and not familiar with actors like Xiao Zhan and Wang Yibo, I was fascinated by their acting. Plus another supporting cast that is also very good, especially Jiang Cheng, Wen Ning, and Wen Qing (because I've seen Meng Ziyi on Ever Night and The Legend of Condor Heroes). After watch The Untamed, I made Xiao Zhan as references in finding films and finally found some, like Joy of Life, Oh My Emperor, The Wolf, and Douluo Continent.
Music : Wonderful. All the music in this drama is very very great. From Opening music to the Closing "WuJi" Soundtrack is very wonderful.
Rewatch Value : This film is worth to be watched again 1000 times (Although some scenes might I skip like when Wen sect attacked Yunmeng,etc.)

I dont know why, but Some scenes will always be in my head, Like when Lan Wangji drunk at 36th episode and almost stole 2 chickens for Wei Wuxian (I can tell that cold people are very funny when they are drunk)
