Demonic

Appropriately, given the nature of its plot, Demonic is a film built largely out of shadows, so if you're watching it on a very small screen it may not work too well. You will need to darken the room for home viewing, even if it increases the urge to hide behind the sofa. Ideally, it's a film to watch late at night when the wind is rattling your windows.

The only special feature here is the trailer, which contains a lot off the best bits but no major spoilers, so watching it first won't hurt
