I went in knowing this was going to be more for fans of the show but I was about 45 minutes in when I realised that this whole film, 1hr 20 mins, is going to take place in a tomb LOL Damn, I was so excited hearing the Untamed theme song play as they marched off on their horses LOL.

Consider this film being more like 2 cut episodes of the Untamed rather than a stand alone movie. It pretty much just gives a little bit more insight into why Huasung does what he does in the Untamed series. I imagine most people get the point anyway but this just gives a little extra information, with a ton of computer game cgi. The brothers were close and the elder brother wasn't such a tough guy, he genuinely cared about people, which is why he kept sparing Yao. And we all know that Hua trusted Yao, so the hurt runs deep.

Alas, again, I was robbed of the Ghosts. The film opened with some promises of giving me what I didn't get in the Untamed and then just resorted to this cgi fight.

Since it's depicted as an extra episode, I would have loved to have had it end with some sort of throw back to the original series like Hua meeting Mo or lingering outside the Mo Manor while the sacrifice ritual begins, or even how he came up with his revenge plot to start with, but it just sort of ends with Hua realising he was tricked by Yao. Revisiting the sets might have been difficult but I would have liked something like that.
Overall, it's really just something for the fans to enjoy esp with they loved the Nie brothers.
