A TV movie that was pretty creepy back in 1991 and still holds up (for the most part).
It dealt with the Smurl poltergeist and the creepy photo below of the real family pretty much proves that it was all true (though based on that logic, photos of my miserable family prove we had a poltergeist of our own... and we didn't [not that I know of]).
Click below for a very simple and spooky scene (I wish modern ghost films would do the subtle stuff more often)...
