it is a slow-burn, psychological movie with numerous chunks of horror and thrilling scenes in it . I really liked how every scene was so full and captivating in itself. The storyline was too intriguing. the whole movie revolves around a teacher(Beth played by Rebecca Hall) whose husband recently shot himself on a boat in a lake near to the house her husband has built . the movie slowly gets interesting as she discovers some secrets about her husband and is eager to know why he had those hidden. The letter her husband has left at his suicide spot which goes "you were there is nothing" comes up with a great twist at the end.
All in all it was a very good movie.
