Writer with mental problems alone in an isolated house. Things go bump in the night and a dark secret is slowly revealed.
Solid story that builds creepiness, then turns promisingly weird at 45 mins. But it falls into the class of psychological thriller using ghosts to beef up the tension.
The acting is good, but the heroine is a dull character. Insomnia, alcohol dependency, sleep paralysis, prescription pills - something seriously wrong with her, but the screenplay shows no quirks, flamboyance, humour. Flat effect, and the dialogue really doesn't help.
In the end her character has nothing to do with it - she was just an accidental conduit. And yet she has the blood of two innocent men on her hands - who cares?
The pace and music are good, but the final sequence is hectic - like they're trying to rush the unsatisfying ending off the stage. And of course another plot that gets the implausible cops-will-be-here-any-minute treatment - always a sign of weak story-telling.
Overall, good build up but it missed the chance to go full ghost and deliver on the weirdness. Make the heroine the villain and you have good horror.
