For a movie that was supposed to give these characters more depth and present their perspective of the events that were part of what happened in The Untamed, I'd say they leaned too far into simplicity in writing. Little to nothing happens, and the whole movie consists for what feels like less than 10 scenes.

The CGI, still a bit awkward at some places, was still a huge improvement from the drama. What's more, I actually did like the last fighting scene. I would remove the "transformer spirits" from the equation though. There was not that much acting to be done, even though the movie was over an hour long, it felt more like 30 minutes - with that I don't think any performance had a chance to shine.

The best aspects of the Fatal Journey was the last shot of Nie Huai Sang that could be described as "ah yes, this is his origin story". Knowing what's coming next, that shot was truly impactful.

Overall, it's clearly movie that targets TU fans only. It's rather meaningless for anyone who does not have prior knowledge of the overall story.

Ps. Adding black eyes for 2 scenes is not enough to call movie a horror.
