UFO (2018) is a compelling independent sci-fi thriller that explores the intersection of mathematics, government secrecy, and extraterrestrial phenomena. The film follows Derek, a brilliant but socially awkward college student whose life changes dramatically after witnessing an unidentified flying object. Using his exceptional analytical skills, he recruits his closest friends to help investigate the sighting, uncovering patterns and connections that suggest something far more significant than a simple anomaly.

Director Ryan Eslinger crafts a tense, atmospheric narrative that relies more on psychological suspense than flashy special effects. The film's strength lies in its character-driven approach, with Alex Sharp delivering a nuanced performance as Derek, capturing both his intellectual brilliance and personal vulnerabilities. The supporting cast, including Gillian Anderson in a key role, adds depth to this mystery that unfolds like a mathematical puzzle.

What makes UFO particularly engaging is its grounded approach to science fiction. Rather than focusing on alien invasions or cosmic battles, the film examines how ordinary people might realistically react to extraordinary circumstances. The FBI subplot adds layers of paranoia and institutional intrigue, creating constant tension as the students navigate both their investigation and external surveillance.

For viewers seeking intelligent science fiction with strong character development and a mystery that rewards attention, UFO offers a satisfying experience. The film's modest budget is compensated by thoughtful storytelling and genuine suspense, making it worth watching for fans of cerebral thrillers and character-driven sci-fi.
