I wanted to watch the movie because Lt. Zhang was there, and he was a gem!
That aside, the overall plot/story was a typical detective troupe. Mysterious deaths that needs to be solved. Not too bad. I had early suspicions, but because I second guessed myself, I was wrong in figuring out the perp.

The acting wise, Jiu Ye was pretty much an iceberg for emotions lol Zhang Min En as Lt. Zhang was on point with acting wise. He showed emotion and clear facial expression.

Dubbing is a but iffy in the movie and the CG is rather choppy compared to Chen Pi's story (granted CP's story was mainly outside and didn't need any mechanism environment) So BE WARNED with the CG/Green screen effect.

Left with a cliff hanger/open ending with many questions still lingering, but, overall, it was decent to watch.
