We bring our whole personal history to every movie we see, even ones we’ve seen (many times) before; as we’re in a constant state of change, so the movies we watch seem to change with each viewing.
Watching horror, like watching war films, is a way to experience fear without actually being vulnerable. Vicarious thrills allow us to indulge emotions which, in real situations, would be very unpleasant. We always have the guarantee of personal survival, the threats contained within structured narratives which, traditionally, provided us with a way back to normality.
