I have just watched the movie The Strangers, really good movie. Does anybody have any theories or no anything about the "The Strangers"??

I know the "true story" isn't really anything like that. It's based on the directors personal experience when he was little and was home alone with his sister some people came knocking on their door asking for someone who didn't live there. Later they found out those were people who had been robbing houses where people weren't home and they went up to the doors to make sure people were not there and if they were they asked for someone by a random name.
It is also based on the Manson Murders..

The movie, personally, scared me!
