Frequency

When a rare phenomenon gives police officer John Sullivan the chance to speak to his father, 30 years in the past, he takes the opportunity to prevent his dad's tragic death. After his actions inadvertently give rise to a series of brutal murders he and his father must find a way to fix the consequences of altering time.

Frequency lands as a generally well-received genre hybrid, earning credit for the emotional pull of its father-son radio exchanges and the performances anchoring them, while critics consistently flagged the serial killer subplot as the film's weakest thread. The time-bending premise generates genuine suspense and surprise, but the climax divided reviewers sharply — some found it thrilling, others found it contrived or outright unintentionally funny.
