"Tenet" can be hard to watch due to its complex narrative structure, which involves time inversion and non-linear storytelling. The film requires viewers to keep track of multiple timelines and characters whose actions are influenced by their knowledge of future events. Additionally, Christopher Nolan's choice of dense dialogue, often accompanied by loud sound design, can make it challenging to fully grasp the plot. The film's conceptual depth and reliance on scientific theories about time can also overwhelm audiences, necessitating multiple viewings for clarity.

"Tenet," directed by Christopher Nolan, is a sci-fi action thriller centered on a protagonist, known as the Protagonist, who is armed with only one word—"Tenet"—and fighting for the survival of the world.

The Protagonist teams up with allies to prevent a Russian oligarch from using time manipulation to trigger World War III. The narrative is complex, involving a non-linear timeline and intricate plot twists, challenging viewers to grasp its themes of fate and free will.

"Tenet," directed by Christopher Nolan, received mixed reviews and faced challenges that contributed to its underwhelming box office performance. Key factors included its complex narrative, which confused many viewers, and the COVID-19 pandemic, which limited theater attendance and affected release schedules. Additionally, the film's ambitious themes and intricate time manipulation may have alienated some audiences looking for a more straightforward experience. Despite its high production values and unique concept, these elements hindered its mass appeal.

Both films are directed by Christopher Nolan and share similar themes of complex narratives and time manipulation, but they are standalone stories with different plots and characters. "Inception" focuses on dream manipulation, while "Tenet" explores time inversion and espionage. Although they may share stylistic elements, they are not directly related.
