What Are Film Genres? Activity 2

I recent thriller type genre movie that I've seen would be The Devil Inside. It's mainly a documentary, but it does have a thriller concept. The protagonist's mother was possessed by multiple demons and ended up killing people during an exorcism. She was put into a rehabilitation center in Italy where she was heavily medicated and they assumed that she was sane during the killings. The conspiracy was that she was possessed at the time or that there were things that initiated the killings to occur, but it was really the multiple demons that possessed the mother for her to be the way she was. Later the demons spread and ended up killing everyone that was a part in the process/case.
