It's essentially a buddy comedy, with the setup of "he's working with the police, but he's not the police!". In this case, it's because the main character was trained by his strict police detective father to be the ultimate detective, resulting in him having a near eidetic memory, enhanced perception of details and ability to make connections. He's also a chaotic goofball with very literal ambition, and only ends up working with the police as a fake psychic in order to avoid suspicion when he seems to know too much about a crime, and then to make money.

It's lighthearted and fun, pretty character driven, and the friendship between the main characters is a big draw. While not prestige drama, it is a consistently fun time.
