Gangster delivers a gritty portrayal of the underworld with a narrative that attempts to balance intense action sequences with emotional depth. The story is engaging, though at times the screenplay struggles with pacing, especially in the first half where exposition slows down the momentum. The second half picks up considerably, offering tighter sequences and more focused character development.

The film's screenplay is layered but occasionally feels uneven, with some subplots not fully explored. The pacing improves as the film progresses, maintaining audience interest through well-crafted confrontations and dramatic moments. The songs are minimal and situational, blending into the narrative without disrupting the flow.

Musically, the background score complements the tense atmosphere effectively, enhancing the mood during critical scenes. However, the absence of a distinct music director credit suggests a subdued musical presence, focusing more on ambient sounds and score rather than standalone songs. Cinematography by Alby captures the gritty urban landscape with a raw aesthetic that supports the film's tone.

Mammootty: Powerful and commanding, Mammootty brings depth and intensity to the role of the gangster, anchoring the film with his screen presence.

Nyla Usha: Delivers a confident performance, adding emotional layers to her character that complement the lead.

Sekhar Menon: Provides solid support with a convincing portrayal of a key associate in the gangster's world.
