Review of PG-13 rated "The Haunting in Connecticut"
"Fact or fiction, it all comes down to whether or not the story can serve as the foundation for a good old-fashioned scary movie. In that capacity, The Haunting in Connecticut is fairly serviceable, delivering the creepy chills without relying heavily on violence and gore.
While it doesn't rely on violence and gore, the editing is often visceral and intense. Most of the scares involve ghostly corpses with incantations etched into their skin, and in one creepy flashback, we see a mortician prepare to remove an eyelid from a body. (We don't see it, but still … yeesh.) Most of the ads play up a bizarre scene with a boy spurting "ectoplasm" (paranormal slime) from his mouth—weird and creepy, yes, but rather fake-looking and more on par with Ghostbusters than The Exorcist."
