I don't get it...

Ok so this is a moovie about the paranormal and ghosts and that yeah?

You shouldn't approach this as a ghost story. It's not supposed to be scary in the sense you mean. It's an exploration of our attitudes to life & death, and how we view the idea of some sort of afterlife. It's a very human & humane story, one that most people can or should be able to relate to as they live their lives over the years & decades. Have you ever had someone you know & love die? Have you wondered why it happened, if there's some deeper meaning, if they're truly gone or whether they might survive after death in some way, or that we need them to survive after death because of the black hole of pain & loss when they're gone? Have you never even remotely wonder5ed about these things? Most people do wonder about them at some time or another. This is a movie for all those who do wonder ... which is the majority of the human race.
