This film’s excessive length feels like a direct result of Christopher Nolan's influence. The initial premise holds promise and is quite intricate, and the opening thirty minutes establish things in an engaging way; however, what follows proves disappointing due to too much talking and a lack of suspense before arriving at an ending that seems unbelievable to someone with experience in live television—it’s almost absurd. "Daniel" (played by Josh O'Connor) narrowly avoids trouble from the unpleasant "Noah" (Colin Firth), who is trying to recover a strange, glowing object Daniel has taken. Simultaneously, television weather presenter "Margaret" (Emily Blunt) undergoes an odd change; she suddenly finds herself able to speak Korean fluently and then faints at the thought of warning Kansans about impending hail. How could these two occurrences possibly be related? That’s what we discover as a lengthy and somewhat repetitive series of car chases slowly explains a plan being orchestrated by "Hugo" (Colman Domingo – who is the only performer so far to genuinely need an American accent), a plan that remains unclear even to him! Is there something otherworldly at play here? Meanwhile, the world faces another potential disaster due to military actions in Korea, leading one to wonder if humanity is doomed and if all this screeching of tires amounts to nothing. The film will undoubtedly appeal to conspiracy theorists, but its lack of character development leaves it feeling superficial—it's missing depth, detail, humor, and heart. It seems to be over-relying on the director/writer’s reputation and some visual and occasional animatronic effects that have become commonplace since "E.T." appeared roughly forty years ago. It isn’t a terrible film; it simply doesn’t reach its potential, and I doubt it will stick with audiences for very long. Still, seeing it in a cinema is worthwhile; it would appear rather dull on television, and the fast-forward button might become hard to resist.
