The creaks you hear in the middle of the night might be a product of an old house.
Or they might be the sounds of someone walking through your halls uninvited.
Here are the main reasons why the concept is so scary:
The storyline is alarmingly realistic.

Sony Pictures Entertainment
Unlike most horror movies, there arent any ghosts or supernatural creatures lurking around the house in The Intruder.
There is only a man.
Home intruders are more common than you think.

The majority of break-ins are committed by someone who lives in your neighborhood.
That is because they are able to learn your schedule.
They know when you leave for work.
They can see when your car leaves the driveway and when you open your windows.
Someone who has actually livedinsideyour house would know even more.
They would know which floorboards creak.
They would know which windows jam.
Its extra incentive to change the locks when you move into a new place.
You never know who still holds a key.
You are never safe not even in your own home.
3.7 million homes are broken into each year.
That means seven homes are broken into every minute of every day.
Pieces of what happen in this film could happen to you.
You never know what someone is capable of doing.
If someone is going to kill you, you probably know them.
58% of homicide victims know their killer.
They are either friends, lovers, or casual acquaintances but they know each other personally.
In this film, the wife feels bad for the intruder.
She thinks he is lonely.
She does not realize she should fear him.
She proves its all too easy to read a person wrong.
No one sees themselves as a villain.
He believes he is doing the right thing.
He does not have evil intentions at least, he does notthinkhe has evil intentions.
That is how crime works in the real world.
Every person sees themselves as the good guy, which is what makes them so dangerous.
Watching this film will make it hard for you to sleep at night.
The creaks you hear in the middle of the night might be a product of an old house.
Or they might be the sounds of someone walking through your halls uninvited.
Sometimes, its hard to tell the difference.
