My personal favorite kind of horror movie - one in which shocking, disturbing images do the trick, popping up here and there in a mystery-driven premise. Not too self-consciously restrained (like critics favorites The Babadook and It Follows) and not too over-the-top either (like them damn torture porn things).
Like most horror movies things start out promising and moves on nicely with an interesting plot and great tension and pretty effective scares. HOWEVER... unfortunately things end up in a rut I´m sorry to say and the ending is pretty stupid and does not really deliver the way I wanted it to. The best bit is Ted Levine's take on Hunter S. Thompson which is quite hilarious.
