The story is set in a desolate New York City, three years after a genetically engineered virus intended to cure cancer has mutated and wiped out most of humanity. Those who were not killed by the virus have transformed into nocturnal, aggressive creatures known as “Darkseekers.” Robert Neville (Will Smith), a brilliant scientist and the last known human survivor in the city, spends his days scavenging for supplies, working on a cure, and trying to find any other survivors. His only companion is his loyal German Shepherd, Sam.

Will Smith’s performance as Robert Neville is the heart of the film. He portrays Neville’s loneliness, determination, and gradual descent into despair with emotional depth and nuance. Smith effectively conveys the weight of being the last man on Earth, balancing moments of vulnerability with his character’s resilience and resourcefulness. His interactions with Sam provide some of the film’s most poignant moments, highlighting the profound bond between man and dog in a world devoid of human connection.

The film’s depiction of a deserted New York City is visually striking. The once bustling metropolis is now overgrown with vegetation, abandoned cars, and decaying buildings, creating a hauntingly beautiful backdrop for Neville’s daily routine. The visual effects team did an excellent job of transforming the city into a post-apocalyptic landscape, enhancing the film’s atmosphere and sense of isolation.

The Darkseekers, while central to the film’s tension, have been a point of contention for some viewers. The creatures are rendered using CGI, which, although effective in creating a sense of menace, can sometimes appear less realistic compared to the practical effects. Despite this, their presence adds a constant threat, and the sequences involving them are intense and suspenseful.

“I Am Legend” also delves into Neville’s psychological state, exploring the effects of prolonged isolation and loss. Flashbacks reveal his past life, the outbreak of the virus, and the loss of his family, adding layers to his character and explaining his relentless pursuit of a cure. These glimpses into his past help to humanize Neville and provide context for his actions and motivations.

One of the film’s most emotionally charged moments comes when Neville is forced to euthanize Sam after she is infected by the Darkseekers. This heartbreaking scene underscores the harsh realities of Neville’s existence and serves as a turning point in his character’s journey.

The film builds towards a climactic confrontation with the Darkseekers, culminating in Neville’s discovery of a potential cure. The original theatrical ending, which differs from the novel’s conclusion, sees Neville sacrificing himself to ensure the survival of two fellow survivors, Anna (Alice Braga) and Ethan (Charlie Tahan), and the potential for a cure. This ending has been criticized for its divergence from the novel’s themes, leading to the release of an alternate ending that aligns more closely with Matheson’s original vision, where Neville realizes the Darkseekers’ perspective and acknowledges his own role as a “legend” in their eyes.

Despite the controversy surrounding its ending, “I Am Legend” remains a compelling and thought-provoking film. It combines elements of horror, science fiction, and drama to create a multifaceted story that resonates on both an emotional and intellectual level. Will Smith’s powerful performance, the film’s atmospheric visuals, and its exploration of profound themes make it a standout entry in the post-apocalyptic genre.

Overall, “I Am Legend” is a haunting and evocative film that captures the essence of human resilience and the enduring hope for redemption in the face of overwhelming adversity. It is a poignant reminder of the fragility of humanity and the strength that can be found in even the most desolate circumstances.
