Worth a watch. I saw the 4.2 IMBD rating, iI decided to give a go anyway It was well acted, well produced with almost no plot holes so common in mysteries. The atmosphere is ideal, a creepy but beautiful old house with too many rooms and isolated in the country away from neighbors and city. Iwas favorably surprised at 1/3 through and still at 2/3 through. It wasn't a slow burn (like many of the reviews reported), nearly every little scene advanced the plot enough to keep my interest: I wasn't just waiting for the inevitable or bored by innocuous and unimportant scenes. . By 2/3rds though I suspected the twist (which is pro forma for this genre) and with few alternative directions it wasn't too hard to guess and that was a little disappointing. . But we still enjoy the lead beginning to put the pieces together and remain enthralled about her outcome.. If I were to find a reason to mark it lower, it's because it doesn't have a supernatural component like most Horror genre films. But it's still a horror/mystery film. The biggest let down is that the end is too ambiguous. We're pretty sure how it will conclude, but there's some doubt and that's troubling. Cudos to the teen actors, I found them believable and delightfully creepy..
