The series’ greatest asset is its production design . Kolkata’s foggy mornings, narrow alleyways, and colonial-era mansions are not just a backdrop but a character in themselves. Cinematographer Sirsha Ray uses a palette of sepia, deep red, and monsoon grey to create a Gothic warmth unique to Bengali cinema. The acting is uniformly excellent. Tillotama Shome as Luna steals every scene, delivering a performance of menacing vulnerability. Sikandar Kher brings a gruff, melancholic charm to Dr. Roy, while Revathi as the hunter provides terrifying moral absolutism.
