1. The Origins: Unbreakable (2000)

Setting the Stage for the Split Universe

Before Split came Unbreakable, which introduced audiences to the idea of real-life superheroes and supervillains. The film follows David Dunn (Bruce Willis), a security guard who survives a catastrophic train accident without a single injury. As he investigates his survival, David realizes he possesses extraordinary abilities, including superhuman strength and an enhanced sixth sense.

David’s journey brings him into contact with Elijah Price (Samuel L. Jackson), a man suffering from osteogenesis imperfecta, or brittle bone disease, which makes his bones exceptionally fragile. Obsessed with comic books, Elijah believes that real-life superheroes exist and that David’s existence confirms this theory. However, Elijah’s dark revelation—that he caused catastrophic accidents, including the train derailment, to find someone like David—establishes him as David’s opposite: the villain known as Mr. Glass.

Themes and Reception of Unbreakable

Unbreakable was unconventional in its approach to the superhero genre. Instead of relying on action-packed sequences, it took a quieter, more introspective look at heroism and villainy in the real world. Though Unbreakable initially received mixed reviews, it has since gained a cult following and is often considered one of Shyamalan’s finest works.

2. Enter Split (2016)

Introducing the Complex Character of Kevin Wendell Crumb

Released 16 years after Unbreakable, Split initially appeared to be a standalone psychological thriller. The story centers on Kevin Wendell Crumb (James McAvoy), a man diagnosed with Dissociative Identity Disorder (DID), which manifests as 24 distinct personalities, known collectively as “The Horde.” Among these identities are the dominant and malevolent “Dennis,” the maternal “Patricia,” and the nine-year-old “Hedwig.” However, the most dangerous identity, known as “The Beast,” possesses superhuman strength and emerges as a terrifying force.

Split follows the story of three teenage girls, led by Casey Cooke (Anya Taylor-Joy), who are kidnapped by one of Kevin’s personalities. As the girls struggle to escape, they witness the terrifying transformation Kevin undergoes when “The Beast” takes control.

The Connection to Unbreakable

In a twist ending, Split reveals itself as part of the Unbreakable universe. The final scene shows David Dunn watching a news report about Kevin’s crimes and recognizing him as another superhuman. This revelation set the stage for the third installment, Glass, connecting the two films and hinting at a larger narrative.

Critical and Audience Reception of Split

Split was widely acclaimed, particularly for James McAvoy’s powerful and nuanced performance. His portrayal of Kevin and his multiple personalities, each with distinct voices, mannerisms, and even physical postures, impressed critics and audiences alike. Split was a commercial success, solidifying Shyamalan’s comeback and fueling excitement for the third chapter.

3. The Conclusion: Glass (2019)

Bringing Together Heroes and Villains

Glass, the final installment, brings together David Dunn, Kevin Wendell Crumb, and Elijah Price. In this film, David, now known as “The Overseer,” works as a vigilante, using his powers to fight crime. When he crosses paths with “The Beast,” the two engage in a confrontation that results in their capture and institutionalization. They are detained in a psychiatric facility run by Dr. Ellie Staple (Sarah Paulson), who specializes in treating people who believe they have superpowers.

Inside the facility, David, Kevin, and Elijah undergo intense therapy sessions aimed at convincing them that their abilities are delusional. However, Elijah, who has been pretending to be sedated, hatches a plan to unleash Kevin’s personalities and reveal their powers to the world. David, Kevin, and Elijah eventually escape, leading to a climactic showdown outside the facility.

Themes and Message of Glass

Glass explores themes of identity, self-belief, and society’s tendency to repress the extraordinary. The film questions what it means to be “super” and whether superhuman abilities would be embraced or feared by society.

Audience and Critical Response to Glass

Glass received mixed reviews, with critics divided on its slow pacing and unconventional ending. However, the film resonated with fans of Shyamalan’s work and those invested in the stories of David, Kevin, and Elijah. For many, Glass provided a satisfying, if complex, conclusion to Shyamalan’s trilogy.

4. Overarching Themes in the Split Series

Psychological Exploration and the Nature of Identity

A recurring theme in the trilogy is the exploration of identity, trauma, and mental health. Kevin Wendell Crumb’s DID stems from childhood abuse, and each of his personalities represents different aspects of his psyche, coping mechanisms, and experiences. Casey Cooke, a survivor of her own traumatic past, finds a strange connection with Kevin, recognizing his struggles and offering empathy even in the face of terror.

Heroism and Villainy in the Real World

The series delves into the nature of heroism and villainy, challenging traditional portrayals of “good versus evil.” David, Kevin, and Elijah are not classic superheroes or villains; they are complex, flawed individuals with extraordinary abilities, who navigate their powers in a realistic, morally ambiguous world.

Society’s Fear of the Extraordinary

In Glass, Dr. Ellie Staple represents society’s fear of the extraordinary. By attempting to convince David, Kevin, and Elijah that their abilities are merely delusions, she reflects society’s reluctance to accept anything that challenges normalcy. Shyamalan questions how superpowers might realistically be viewed—not necessarily with awe, but with suspicion and even fear.

5. The Legacy of the Split Trilogy

Cinematic Impact and Unique Storytelling

Shyamalan’s trilogy is a rare fusion of superhero tropes, psychological thriller, and horror elements, creating a genre-blending narrative that defies easy categorization. With the Unbreakable trilogy, Shyamalan presents a unique take on superheroes, favoring introspective, character-driven storytelling over spectacle.

Cultural and Audience Reception

The trilogy resonates with audiences seeking realistic, human-centered stories in the superhero genre. Rather than larger-than-life battles and intergalactic threats, the Split series explores personal battles, trauma, and the effects of superhuman abilities on ordinary lives. Fans have praised Shyamalan’s storytelling for its originality, complex characters, and thematic depth.

It offers a blend of suspense, horror, and psychological drama that captivates audiences and invites reflection on what it means to be heroic—or villainous—in the real world. M. Night Shyamalan’s trilogy challenges the boundaries of conventional storytelling, leaving a lasting legacy as a visionary, unconventional approach to the human side of superhuman abilities.
