I watched this movie a long time ago and can't remember the name.its about a boy who drowns when he was little and his parents keep him in a basement and kidnap people to feed him there souls,but the last soul he needed was a girl so they escape and they kill the parents and use there souls so he stays alive.I remember when the mom died her head like exploded on the glass door or something like that and I also remember when the girl was kidnapped she was walking on a dirt road.HELP ME its been like 5 years!

I believe it's called "Fair Haired Child" from the Masters of Horror.
