Thilaka Varman (Jayam Ravi), serving a murder sentence, is granted a 14-day parole to reunite with his father and his motherless daughter, Malar (Yuvina Parthavi). Thilaka Varman, eager to meet Malar, becomes the focus of suspicion for police inspector Nandhini (Keerthy Suresh), who is investigating a series of murders. 'Siren,' directed by Antony Bhagyaraj, unravels the mysteries surrounding the murders, Thilaka Varman's incarceration, and his quest to reconnect with his daughter. It also focuses on Nandhini's redemption as she is facing a career setback due to a lockup death.
Jayam Ravi delivers a nuanced performance, portraying Thilaka Varman's longing for his daughter, the weight of 14 years in prison, and the responsibilities of an ambulance driver with depth. However, his somewhat rigid facial expressions could have been more varied. Keerthy Suresh, as the determined police officer, falls short in scenes requiring aggression, relying too heavily on shouting rather than nuanced acting.
Yogi Babu provides sporadic comic relief, while Samuthirakani, Azhagam Perumal, and Ajay deliver stereotypical villainous performances with clichéd dialogues. Among the supporting cast, Yuvina Pardhavi, Thulasi, Chandini Tamilarasan, and Anupama Parameswaran shine in their respective roles.
Selva Kumar RK's cinematography adds depth to the action sequences, particularly in nocturnal scenes. Editor Ruben could have streamlined the over pacing in certain sequences for a smoother viewing experience. The songs 'Kannamma' by Haricharan and 'Netru Varai' by Sid Sriram, composed by GV Prakash Kumar, offer pleasant musical interludes.
Sam CS's background score, though effective in heightening tension in some scenes, occasionally feels overpowering. The film attempts to explore themes of familial bonds, police investigation, social commentary, and revenge, but falls short in maintaining coherence and engagement throughout.
The screenplay's first half, driven by father-daughter sentiment and Thilavarman's character, loses momentum in the second half. Subplots like the 'Lock-Up Death' case and the introduction of new characters lack depth and fail to add intrigue. Despite addressing issues of honor killings and caste politics, the film's execution feels superficial.
Interrogation scenes featuring Keerthy Suresh lack depth, failing to sustain viewer interest. Without compelling antagonists, the protagonist's decisions and actions lack impact.
While 'Siren' attempts to blend elements of revenge, affection, social commentary, and sensationalism, it ultimately falls short of delivering a fresh and engaging storyline.
