It was surprising to read another person’s take on this show expressing they couldn't connect with it; I had a similar experience. Let me attempt to explain why. It seems the core issue is an abundance of side stories. Frequently introducing what are often foreseeable and occasionally hackneyed storylines diminishes and weakens the central premise—an assassin who also works as a police officer. The question should be: will this assassin/cop be apprehended, is there going to be some significant disclosure, or will he continue to evade justice? This ought to be the main driver of the series, but so much else happens that it’s easy to lose sight of it. This excess of narrative elements doesn't just tire out the audience; it also creates a sense of mental conflict and a gradual loss of interest. I definitely struggled to maintain engagement by season two. I don’t think the characters help matters much either. The antagonists feel flat, lacking the social nuance and psychological inconsistencies you would normally expect from people, regardless of whether they are primarily good or bad. It's unfortunate, because this series benefits from a talented cast and impressive production quality. Ultimately, I think the show spreads itself too thin with its various plots, suffers from a shortage of genuine character development, and includes some well-worn tropes. The end result is a series that slowly drains your energy and becomes tedious, making it quite difficult to get through.
