Ghosts and EVP don't exist.
Maybe in a Scooby Doo cartoon, but not in real life. The commercial for this movie was creepy, and yes, it would be creepy and cool if this type of thing did exist, but honestly, I couldn't think of a worse type of hell than to be trapped on this plane of existence after death, trying to communicate with my loved ones or random people via some stupid obscure method, like audio recording, or moving objects, etc, for all eternity. For what purpose?
I'd rather wander the planet if indeed stuck here, instead of silently yelling at the new inhabitants of my house:
"HEY DUMBASS! YOU LEFT YOUR CAR LIGHTS ON! I'M NOW GOING TO GHOST HUMP YOUR GIRLFRIEND, YOU LOSER!"
Would it be cool to talk to my dad again? Of course! Is it possible, or even real? No.
