I don't understand why so many stories end up with a serial killer. To me, killing one person is bad enough. But there seems to be this need in storytelling (esp. movies) to make an evil person MORE evil by making them not just a killer, but a SERIAL killer.
Does this really increase the tension?
I can buy if someone who has killed once (maybe by 'accident' or in a rage/passion) and then, when fear of discovery slam into them like a speeding SUV, they'll kill again to keep the first muder buried. That makes sense to me. But statistically, serial killers, who kill many people fairly indiscriminately is very small. The number of movies and stories is very large.
Are we that desensitized that one murder is not riveting or horrid enough?
Or do publishers/ producers just THINK we are that desensitized?
Or am I just thinking too much. (As Hubby says, "It's just a movie." I think it translates to "Just shut up and watch the movie." =)
