Well, if we're going to make recommendations for recent stuff, I will put my hat in the ring for The Blackcoat's Daughter. It's been three months since I saw it, and it still rattles in my head quite often. It has a potent mix of dripping atmosphere, an involving story, great central characters and a genuinely stunning ending that left me speechless. It's a much quieter film that most, but when it ratchets up the terror and the horror, it is quite unnerving to watch unfold.
Oh right, I forgot about this one! Thanks for the reminder, definitely adding it to the list!
