Can we talk about themes in horror from a sociological perspective? Yes. Ask any horror fan. There is one characteristic in almost every killer in a horror film: motivation. A motivation so strong it drives them to torture, haunting, or abuse.

For decades horror films have been a reflection of society's impact on the individual or the family in the place and time in which they live.

In the 21st century, not only do we see their motivation, we are taking a more critical look. Some filmmakers turn the genre on its head to reveal that the monster is the society we have let ourselves create.

And... sometimes it is still just a cold-blooded killer, otherworldly enigma, or bad-ass monster.
