The movie seemed to use the mixing of the present and future to create suspense and confusion for the characters and for the viewers. This confusion between what was taking place (the real) and what was not real. However I found the most interesting part was how ugly the woman / killer was in the end. The horror created in the film, at least for me, came more from the looks of the old woman not an intimidation factor. The old woman appeared as a small child while she was being chased but in the end was the complete opposite a shriveled up old woman.
This movie also appeared to be using the use of themes to a greater extent than films we have watched so far this semester. The focus on water and glass breaking came to the culmination in the end of the film when John has died and kicked out the window next to the canals. Also I have to admit I did not expect the image of the old woman in the red coat to appear in the image on the slide bringing the film full circle like some of the films we have watched this year.
