White Noise refers to a phenomenon known as EVP (Electronic Voice Phenomena), believed to be the voice of the dead on electronic media such as radio signals or TV snow.
Jonathan Rivers' wife, Anna, disappears. A man tells him that his wife is dead and talking to him. She's later found in her car, which had crashed into the water. Jonathan meets with the man, who is an EVP expert for over twenty years. He shows Jonathan how EVP works and he starts hearing from his wife. But, not all EVP spirits are good.
The story is simple and fairly easy to follow, for the most part. There are some obvious plot holes that leave a few BIG questions unanswered; which ruined an otherwise (possibly) good story. The story is fairly original because it's done with EVP but, if NOT for the EVP, I've seen this done in movies such as Witchboard, just a variation of the medium used. But it's fairly engrossing and the time goes by fast.
The atmosphere isn't one of impending doom, building up to one exciting climax. It's a bunch of little time-sensitive mysteries. So it's like a racetrack with speed bumps and one final lap unobstructed.
The cinematography is straight on without any unique shots. There's few SFX used besides the EVP signals and the final scene. There's not really gory.
The cast is adequate, no one really stand out. Michael Keaton is the main character and is on screen for almost every scene. He does good but not up to par with his past roles. And where has the old Michael Keaton gone? He hasn't had a starring role in a hit in about seven years.
Overall, a fairly entertaining film if you can try to get past its plot holes. It's fun to think up explanations but many viewers just want entertainment. There are a few scares and some disturbing ideas tossed around but mostly what is not shown rather than what is. It disappointed me because I like Keaton and had higher expectations after seeing the previews.
