Not my usual genre, which actually made this movie kind of a thrill to watch since it was a lone wolf amongst my usual movie fare. I enjoyed the tension and slow burn. The film was cinematic and starkly beautiful. I thought the cast was terrific. Dark nights and rain added atmosphere and tension. I got the feels at the end - ahhh! Can't give it away, but it got to me. Well shot, and startlingly frightening. Yes it's a slow burn but dig deep and if you're in a relationship you'll find yourself identifying with these two folks as they struggle to get through an unusually troubled, difficult marriage.
