White noise is a 7/10 film. The ending has no real justification. I had to look on that endingspoilers website to find out the meaning of how it concluded because it was confusing and strange.
Anyway, E.V.P. does not work, it's bullshit. You see, all they do is get wierd methods of obtaining random pictures of light and objects, and then when they see something they fit it the picture in a puzzle.
For example if you were to look at this picture and see this girl crying -
A typical E.V.P. event would involve a very small picture of lets say, what appears to be a pillar with a ring pattern on it. They would conclude that this is the middle finger of the girl with the ring.
And it's not just a conclusion, it's actually waiting for a perfect match. Why people do this is the same reason why people think John Edwards is real, and why people think psychics are real... and why people think star signs are real...
P.S - The film isn't that scary. There are maybe one or two 'jump' parts but this doesn't compete in the scary factor league. Hell, the Silent Hill series scared me a billion times more than this movie ever could...
