Big Brother attempts to blend action and family drama with a screenplay that leans heavily on Mohanlal's star power. The story is straightforward, focusing on themes of protection and familial bonds, but the screenplay lacks subtlety and often resorts to clichés. The pacing is uneven; the first half sets up the characters and conflict at a steady pace, but the second half becomes predictable and drags with repetitive confrontations.

The songs composed by Deepak Dev are situational but do not leave a lasting impression, serving more as fillers than highlights. The background score is adequate, supporting the emotional and action sequences without overpowering them. Cinematography by Jithu Damodar captures the locales well but does not offer any particularly memorable visuals.

Overall, the film caters primarily to fans of Mohanlal and those who enjoy conventional action dramas, but it falls short of delivering a fresh or engaging cinematic experience.

Mohanlal: Charismatic and commanding as the lead, Mohanlal carries the film with his screen presence despite a weak script.

Arbaaz Khan: Provides a solid antagonist role but with limited scope.

Anoop Menon: Adequate in a supporting role, adding some depth to the narrative.

Honey Rose: Underutilized with minimal impact.
