Sinister (2012) dir. Scott Derrickson; starring Ethan Hawke, Juliet Rylance
Finally caught up to this and the moral of the movie is, having kids is scary.
This is one of the earlier Blumhouse productions, and a surprisingly effective horror movie thanks in part to Ethan Hawke's performance. He plays a father and a writer of true crime books whose last books haven't done as well as his first. He's desperate for another best-seller so he moves his wife and children to the site of the murder of another family to help him write his next book. Most of a family, really; the youngest daughter disappeared, apparently kidnapped.
Well, of course, there's more to it than that, and Derrickson and his writers -- note C. Robert Cargill is one; he is also a novelist and short story writer I haven't read, but I'm thinking I'd like to -- do a good job of gradually dropping clues and ratcheting up the tension. According to Wikipedia, the idea for this came from a nightmare Cargill had after watching The Ring; not knowing that as I watched, I thought there were parallels since the movie features the use of a Super-8 camera.
What I most appreciated was the simplicity and directness of the special effects, which create an eerie atmosphere. And it reminded me that, when used judiciously, a jump-scare can still be effective without being hokey.
