Peg O’ My Heart Review: Strong Acting Can’t Save a Clumsy Script

Peg O’ My Heart wastes no time pulling you into its psychological fever dream. The film opens on a version of Hong Kong choking on the fumes of the 2008 financial crash, a landscape of urban decay that mirrors the inner turmoil of its inhabitants.

This is a city presented not as a bustling metropolis, but as a fertile ground for anxiety and guilt. We are introduced to our guide through this world, Dr. Man, a young psychiatrist whose intense, boundary-breaking methods are born from a conviction that one must treat the source of a trauma, not just its symptoms.

His methods, however, are about to be tested. He encounters Choi, a taxi driver whose life is disintegrating. Choi is plagued by a sleep disorder that has erased the line between his waking hours and his terrifying nightmares, making him a danger to himself and those around him.

The film establishes its core narrative engine here: a doctor’s investigation into a patient’s fractured mind, a process that threatens to shatter his own fragile sanity. What unfolds is less a medical drama and more a psychological puzzle box, where dreams and reality become indistinguishable battlegrounds for two tormented men.

A Story Drowning in Style

The film’s most immediate and undeniable strength is its arresting visual language. Director Nick Cheung demonstrates a confident, bold aesthetic, constructing a world that feels genuinely hallucinatory.

The screen is filled with potent, nightmarish imagery: Choi is haunted by inky, monochrome visions of demonic figures; sequences of sudden body horror are jarringly effective; and surreal tableaux, like a double-decker bus suspended silently over a calm sea, stick in the mind.

The most bizarre and effective of these is the recurring motif of the title song, an old-timey Vaudeville tune that serves as the soundtrack for Choi’s wife’s delusional musical fantasies. For its first act, the film’s commitment to this dream logic is intoxicating, creating an unsettling atmosphere where the characters’ mental states are made terrifyingly palpable.

The problem is that the screenplay cannot keep pace with the direction. The story begins as an abstract, psychological horror film but then makes an abrupt and awkward pivot into a conventional investigative procedural.

As Dr. Man plays detective, digging into Choi’s past, the narrative structure becomes disappointingly familiar. This shift dissipates the carefully built tension, and the stunning visuals, once integral to the experience, begin to feel like disconnected, stylistic flourishes in a story that has lost its nerve.

Strong Performances in a Flimsy Frame

The cast works diligently to ground the film’s chaotic narrative. As Dr. Man, Terrance Lau gives a compelling performance, embodying a dedicated professional whose commitment to healing others feels like a desperate attempt to outrun his own psychological wounds.

He is a believably flawed protagonist. Nick Cheung, pulling double duty as director, is extraordinary as the tormented patient Choi. He skillfully portrays the two facets of the character: the broken, mind-shattered taxi driver of the present and the arrogant, successful financial analyst of the past.

Fala Chen adds a layer of deep tragedy as Choi’s wife, Fiona, a woman so lost to schizophrenia that she can only connect with her husband in imagined musical numbers. Her moments on screen are some of the most sadly memorable. Yet, these fine performances are ultimately underserved by the character writing. The actors bring an intensity that the script fails to support with sufficient depth.

The central relationship between Choi and Fiona, which should be the story’s emotional anchor, is explained to us but never truly felt. The characters, for all the actors’ efforts, too often feel like pawns being moved around a visually elaborate but emotionally hollow game board.

A Diagnosis Left Unfinished

The film is not short on ambition. It reaches for several weighty themes: the corrosive nature of capitalist greed, the long shadow cast by financial trauma, and the complex archetype of the “wounded healer.”

It raises an interesting question about what happens when a caregiver is just as damaged as the person he is trying to save. These are worthy ideas, but they are presented more than they are explored. The commentary on societal ills and mental health remains largely on the surface. This shallow exploration is most evident in the film’s resolution.

After a long journey through a messy, chaotic psychological landscape, the central mystery is tied up with an abruptness that feels entirely unearned. This tidy ending betrays the very nature of the world the film worked so hard to establish. Peg O’ My Heart stands as a showcase for a director with a remarkable eye for crafting powerful images, but it also reveals a storyteller in need of a script that can match his visual talent.

Peg O’ My Heart premiered at the Far East Film Festival on 30 April 2024 and opened theatrically in Hong Kong on 27 March 2025 via Golden Scene.
