"House of Ninjas" offers an entertaining blend of action, humor, and conspiracy, wrapped in a tale of family dynamics with a secretive twist. Set in a household where three generations coexist, each member grappling with their own desires and obligations amidst a dark family secret, the narrative unfolds with a mishap from a past mission looming over their present lives. Soichi, the patriarch, strives for normalcy while managing a failing sake brewery, while Yoko, the matriarch, seeks excitement through shoplifting. Their children, Nagi and Haru, navigate their own paths amidst ninja traditions and modern desires, while Grandma Ninja keeps a watchful eye, especially on the youngest, Riku.

The film strikes a balance between humor, romance, and intense fight sequences, with well-choreographed ninja battles and amusing moments, particularly the grannie-on-grannie ninja action. However, the occasional inexplicable decisions and lack of interpersonal communication among the characters may leave viewers scratching their heads. Nevertheless, the ensemble cast delivers commendable performances, capturing the essence of their characters, from Haru's solemn demeanor to Nagi's mischievous spirit.

Notably, the soundtrack, featuring tracks like Graham Nash's "Our House" and several by The Zombies, complements the scenes effectively, enhancing the overall viewing experience. While "House of Ninjas" may not cater to those seeking a serious, blood-soaked drama or a romantic saga, it offers a refreshing take on the ninja genre, blending high stakes with light and dark humor, family drama, and a touch of romance. Despite its flaws, the series proves compelling and entertaining, earning a solid recommendation for those in search of a unique and enjoyable experience.
