Viktor Prentovski’s review published on Letterboxd:
Frequency is a really good movie about a father and a son. Time travel is a key element in this movie. The son is communicating with his father. The son is in year 1999, and the father is in year 1969. It has many paradoxes and illogical stuff, but I don't care about them. This is not a time travel movie. It's a movie about the relationship of a father and a son. And it's touching, emotional and captivating. A really good family movie.
