Honestly, I found this show to be just okay.

The main issue with this show is the writing, which felt uninspired and lazy at times. Characters would find answers/clues sometimes too conveniently to move the story along. Thus as a result, the investigation did not feel super compelling to me. Additionally, Seo Hui was criminally underwritten. That character had an underwhelming amount of development/growth, and wasn't given much to do. Also, I didn't like how in the beginning the (only) female detective was often the comic relief as a result of her foolishness. I've seen this type of humour is older dramas and thus it felt stale to me, and a little offensive to still be seeing token female characters in male-dominated work environments portrayed like that nowadays. That being said, the show definitely had its moments that were either intense or intriguing.

The acting is really the best part of this show. Lee Min Ki gives a great nuanced performance as a character completely different from his most recent drama work, thus further proving how exceptional he is of an actor. Lee Yoo Young was good as well with what she is given, I just wished she had more to work with. I also really liked Kim Shi Eun as Jin Kyung and Yoon Jong Seok as Ho Gyu, who both were endearing and truly earnest. This is probably just me, but I didn't really like Seo Hyun Woo as In Dong Gu, as the performance felt one-dimensional and it really felt like he was "acting".

Music was alright, I like the 80s inspiration. But also it didn't really suit the style and tone of the show, thus it felt like a superficial attempt to be "trendy".

Reading this over, I sound a little harsh but I just wished the writing/story could have delivered the same level as the cast did.
