Urumi is a visually stunning period drama that showcases Santosh Sivan's prowess as both director and cinematographer. The film's content is rich with historical references and cultural depth, though it occasionally leans towards melodrama. The screenplay is ambitious, attempting to balance a sprawling narrative with multiple characters and subplots. The pacing in the first half is deliberate, setting up the historical context and character motivations effectively, while the second half picks up momentum with action sequences and emotional confrontations.

The film's music and background score complement the epic scale, with traditional instruments and haunting melodies that enhance the mood. However, the songs are few and placed sparingly, which suits the tone of the film but might feel less engaging for audiences expecting a typical commercial musical experience. The BGM is particularly effective in battle scenes and moments of tension, adding to the immersive experience.

Overall, Urumi stands out for its technical finesse and ambitious storytelling, though its length and complexity may challenge some viewers. It is a commendable effort in Malayalam cinema to portray a significant historical period with grandeur and emotional depth.
