Really, really good.

Rating: 9/10 (26 February 2015)

If you're like me and aren't really a b-movie "shock and gore" fan and just enjoy a well crafted film then you will enjoy this. If you want jump scares and fountains of blood I'd stay away.
This is a disturbing and deeply unsettling psychological thriller that is incredibly well acted by both it's leads, and ultimately something that will be crawling around the back of my brain for a few weeks.
I'm guessing all the 1 star reviews here are due to this film being marketed poorly. I had the advantage of seeing it with absolutely zero expectations, I literally had no idea what it was about or even what genre it was, my wife just told me "you have to check this out!" and that was it. I'm assuming it must have been mass marketed as a "Horror! Scary!" movie, which, while it is extremely unnerving is not at all what this movie is.
