Being able to achieve a modicum of suspension of disbelief is crucial when watching horror and movies with supernatural elements. Here though, the characters are just unbelievable, they do not behave like any normal human exposed to the demonic/angelic would. And a blind medium/tarot card reader? Using a white "seeing cane" in her own living room? good grief that was just cringe.
Even the cop on crime scenes is silly. The main character walks around with the actual evidence instead of photos of evidence? Yeah, that would happen.
The characters are 1 dimensional, and it is next to impossible to feel for them, even the fiance of the hero, you just don't care when she is in danger, it's really that bad as far as characters go. The dialogue is bad and cheesy. It's a shame really, it could have been good with a better director and editor.
