Set against the dusty, tense backdrop of the Andhra Pradesh–Tamil Nadu border in the mid-1990s, Thadayam aims to be a slow-burning serial killer drama with psychological depth. What it ultimately becomes, however, is a series that builds atmosphere and character with care but stumbles when it comes to payoff. Anchored by a solid, restrained performance from samuthirakani, this preachy crime drama has flashes of brilliance but struggles to convert them into a gripping whole.
Story
The narrative unfolds in 1996, a year after a counsellor’s murder, when a chilling string of killings erupts along the border. The victims—both men and women—are murdered brutally, with a peculiar pattern: waist chains and wedding chains are stolen, and a question mark drawn in blood marks the crime scenes. The repetition is deliberate, ritualistic, and clearly symbolic.
SI Adhiyamaan, played by samuthirakani, is initially dismissed as incompetent by his own department. He is a cop who seems to have internalised defeat—numb to violence, dulled by bureaucracy, and distracted enough to call a tuition student from a crime scene landline to cancel class. That moment, though odd on the surface, quietly reveals a man who has grown desensitised to horror and conditioned to multitask survival within a broken system. It is SI lakshmi (Sshivada) who recognises the spark in him and pushes him into the investigation.
The show doesn’t play a cat-and-mouse game with the audience; the killers are revealed early. The tension is meant to come from how the cops close in on them. Yet, despite an intriguing premise, the narrative feels rushed and scattered. The motive—when finally revealed—leans heavily on moral arguments rather than convincing logic. A glaring question lingers: why commit nearly 70 murders to conceal seven? The script poses it but never answers it convincingly.
Parallel to the investigation runs Lakshmi’s personal arc—her struggle against patriarchal expectations from her fiancé’s family and the constant undermining of her authority. While this track attempts to add emotional layering, it rarely intersects meaningfully with the core investigation. It exists, but its narrative weight feels questionable.
Performances
samuthirakani stands tall as Adhiyamaan. His portrayal is understated and internalised—less about fiery heroism and more about quiet endurance. He convincingly plays a man worn down by systemic neglect and professional humiliation, yet capable of rising when pushed. His performance gives the series emotional credibility even when the writing falters.
Sshivada brings sincerity to lakshmi, portraying both vulnerability and determination. Her track, though underutilised narratively, benefits from her grounded acting. The antagonists, though chilling in intent, lack the psychological depth required to make their actions resonate. Since the audience already knows who they are, the script needed to invest more in their complexity—and it doesn’t quite get there.
Technicalities
The period setting works in the series’ favour. The absence of mobile phones and wallet PLATFORM' target='_blank' title='digital-Latest Updates, Photos, Videos are a click away, CLICK NOW'>digital surveillance adds authenticity and restricts the investigation to old-school policing methods. The production design captures the rural 90s aesthetic effectively—dusty stations, landline calls, and border-town tension.
The background score amplifies unease during the murders, though it occasionally overplays emotional beats in the later episodes. Cinematography lends a gritty tone that complements the subject matter. Editing, however, is inconsistent. The pacing feels hurried in critical stretches, especially during the climax, where revelations are delivered abruptly rather than organically.
Analysis
Thadayam wants to be more than a serial killer thriller. It aspires to explore moral responsibility, social structures, and the psychological toll of violence. The problem is not the ambition—it is the execution.
By revealing the killers early, the series bets on emotional and investigative tension. But once the identities are known, the narrative fails to build escalating stakes between cops and criminals. There is little dramatic friction when they finally confront each other.
The final stretch leans heavily into moral messaging. The explanation behind the murders attempts to distinguish seven lives from the rest, introducing a socially responsible angle that feels sudden rather than earned. The tonal shift from crime investigation to preachy commentary dilutes the impact. Instead of delivering a chilling conclusion, the series opts for a moral lecture.
At its core, Thadayam succeeds in crafting a compelling protagonist but fails to construct a narrative sturdy enough to support him.
What Works
• Samuthirakani’s layered, restrained performance
• Authentic 90s setting and rural atmosphere
• A chilling murder pattern that sparks intrigue
• The idea of a morally conflicted investigation
• Grounded cinematography and tonal consistency in early episodes
What Doesn’t
• Weak narrative focus and rushed pacing
• Unconvincing motive behind the large-scale killings
• Underdeveloped antagonist psychology
• Lakshmi’s parallel track lacks narrative impact
• Preachy climax that undercuts suspense
Bottom Line
Thadayam begins as a gritty 90s borderland thriller with psychological depth, but slowly morphs into a moral sermon that forgets to deliver emotional or investigative payoff. samuthirakani gives it heart, but the writing doesn’t give him the knockout ending he deserves. It’s not a misfire—but it’s not the sharp crime saga it could have been.
