Strengths
Original Premise – Elite fighters made police officers sound ridiculous and new, with each character bringing new abilities that influence the action scenes as much as his struggle.
Action Sequences – The series takes pieces of boxing, fencing, gunplay, and wrestling maneuvers and integrates them into the action sequences, and it culminates in a visually exciting and realistic combat.
Strong Performances – Park Bo-gum’s development into an action leading man is impressive, as he has charm and depth. His dynamic with Kim So-hyun brings warmth to the general camaraderie.
Blend of Humor and Emotion – The tone transitions nicely from lighter moments and intense action, and thus the show is great for casual and critical viewers alike.
Content-packed themes – Although there is action blockbusting, the drama also touches on corruption, misuse of authority, and suffering of athletes attempting to shun the limelight.
Areas of Improvement
Slow Starts – The initial episodes take some time to gain momentum, which may prove wearing for the audience until the story really takes off.
Romantic Plotline – The romance is underdeveloped and occasionally interferes with the overall plot despite chemistry between the leads.
Undeveloped Side Characters – Some supporting teammates lack sufficient backstory or development in comparison to the central cast.
Indeed. Good Boy gives the action-cop genre a welcome twist in sports-action fight scenes, tear-inducing team scenes, and timely themes. This works best for audiences who enjoy ensemble casts, redemption tales, and high-octane action sprinkled with comedy.
