A very dark, sometimes shocking and visceral drama. TRIGGER WARNINGS definitely needed, as torture, abuse and rape (that bit isn't graphic, but obvious) are included.
A prosecutor with a tragic past, up against an intelligent, sadistic serial killer who carries all the text book trade marks of a psychopath.
The story had a strong start, but as the episodes unfolded, some aspects became overdone and too much; from the often inept police, that seemed almost comical in their approach, to the obvious connection that several characters and places obviously had to the perpetrator, being woefully overlooked, even when visited.
Several characters were too quickly 'marked' and other avenues that should have continued to be investigated, weren't. It was all a bit haphazard at times, especially given the severity of the case.
However, this was the 90s ~ the era being well portrayed I thought (even if I don't come from Taiwan, I recognised the vibe), when perceptions were different (and sadly still exist in too many cultures).
The acting of the MCs carried the story, however, and so it still made for a compelling watch.
The lengths the prosecutor ended up going to, to get his man, were life changing and cathartic; the transformation of that character was very cleverly done.
There was some overacting at times, but overall, many characters were excellently played. The actors that stood out for me, head and shoulders, were Chen Bo Zheng as a victim's grandfather (I so like this older actor ~ he always plays his characters in an understated way and is good to watch even if the drama isn't!); the actor who played Chris Wu's character's Uncle, so convincingly; and Chris Wu himself in the leading role.
The plot did leave a lot to be desired at times, but it was still a very watchable drama.
