Frequency (2000): An accidental cross-time radio link connects father and son across 30 years. The son tries to save his father's life, but then must fix the consequences. (7.3)
Director: Gregory Hoblit
Stars: Dennis Quaid, James Caviezel and Shawn Doyle
Not quite time travel, but it uses cause and effect methods across a 30-year gap. If you pass a known info down to 30 years back and that has major effects for you today, and you don't have that info, then you can't pass that info back. The sentimentality has taken precedence over the time-warped cause and effect sequences. This is not a well-thought-out story. But the acting is good enough and the storytelling is suspenseful to keep the viewer interested the whole time. My Rating: 6.0
