At Thaenkaadu, Rishi is assisted by the forest officer Sathya, played by a remarkable Srikrishna Dayal. Sathya represents the crucial link between humanity and nature, a benevolent soul devoted to mother nature. Amidst the mist and the lush greenery of the jungle, a forest spirit named Vanaratchi saves the jungle and its inhabitants — a pivotal plot point that takes the show into the realm of supernatural horror. The film soars high in the depiction of the horror elements. The atmosphere bathed in the dark and mist leaves heart-thumping eerie moments. It earns extra points for not relying on jump scares, typical creature-feature techniques, or jarring scores. Instead, it delivers a captivating experience with a tightly woven immersive script. The show follows the formula of a police procedural: expository table discussions about the case, mysteries being unravelled as a new mystery evolves, red herrings, and chase sequences.
The distinctive style we have seen in Girish's previous films like Thanneermathan Dinangal (2019) and Super Sharanya (2022), is all the more pronounced in Premalu. Remember the quirky and eccentric Ravi Padmanabhan (Vineeth Sreenivasan) of Thanneermathan Dinangal?
