UFO (2018) is a compelling sci-fi thriller that blends mathematical intrigue with classic extraterrestrial mystery. The film follows Derek, a brilliant but socially awkward college student whose life changes dramatically after witnessing an unexplained aerial phenomenon. Using his exceptional analytical skills, he recruits a small group of friends to systematically investigate what they saw, uncovering patterns that suggest something far more significant than random lights in the sky.

Director Ryan Eslinger creates a tense, grounded atmosphere that makes the extraordinary premise feel remarkably plausible. The film's strength lies in its character-driven approach, with Alex Sharp delivering a nuanced performance as Derek, whose mathematical obsession becomes both his greatest asset and his vulnerability. The supporting cast, including Gillian Anderson in a key role, adds depth to this multi-layered narrative about perception, truth, and institutional secrecy.

What makes UFO particularly engaging is its intelligent approach to the genre—it's less about flashy special effects and more about the psychological and procedural aspects of a potential close encounter. The cat-and-mouse dynamic with pursuing FBI agents adds constant tension, transforming a personal investigation into a high-stakes pursuit of truth. For viewers who appreciate thoughtful science fiction that prioritizes character development and realistic mystery over spectacle, UFO offers a refreshing and suspenseful experience that will keep you questioning what's possible right up to its thought-provoking conclusion.
