8 Horror Movies Twice As Terrifying On The Second Watch

8. The Eye

If you've never seen the original Cantonese version of this film - and not the hideous Jessica Alba Americanized version - then you are in for a real treat.

The concept is quite simple: a blind woman can now see after an experimental surgery, but struggles to deal with an unexpected side effect - she can also see spirits.

This is handled beautifully during the film, as the cinematography often places the viewer in the protagonist's shoes, meaning that we, like her, aren't entirely sure what she's seeing.

And in later viewings, that effect is deepened. Throughout the entire film, you see hints of faces everywhere, heightening the tension. It's almost as if the ghosts are hovering around her, waiting to be seen, which is a truly terrifying thought.

Need an example? Whether intentionally or not. As she rides the train, there's a face in the window near her, and it is never acknowledged.
