The series serves as a spin-off to the 2022 supernatural comedy film Marry My Dead Body, with Greg Hsu, Gingle Wang, Ma Nien-hsien, and Flower Chen reprising their respective roles, while Lulu Huang, Ng Ki-pin, and Da-her Lin join the cast.

[12] Jin teased the production of a spin-off series in May 2023 while marketing Marry My Dead Body in Korea,[13] followed by an official announcement, with Yin Chen-hao joining Cheng as co-director and co-writer in August.

[14] In July 2024, Flower Chen was also confirmed to reprise his role,[18] while director Cheng Wei-hao revealed that Austin Lin, one of the three co-leading actors from the previous film, would not join this project, as his character had been killed off and maintaining story continuity would not allow for his return.

[25][26] James Marsh of South China Morning Post gave GG Precinct 2/5 stars, critiquing that while the series attempts to blend grit and comedy with its misfit cop squad investigating a serial killer, the show ultimately falls short due to underdeveloped character dynamics and relationships, resulting in a lightweight and unresolved final product.

[29] Berton Hsu, writing for The News Lens, highlighted the series' ambitious effort to match Calendar Studios' previous commercial successes by blending elements of American sitcoms with Japanese-style humor, showcasing a unique and avant-garde approach that may surprise fans of the prequel Marry My Dead Body, though the diverse comedic styles and character portrayals could elicit mixed reactions from audiences.
