I am confused about the last shot of the movie. The close up of the rusted container. Did that have some meaning? I found the movie interesting and disturbing. The acting was well done. After reading many of the comments on this movie I agree there are many questions left unanswered. I assume that was the director's intent. Or as one writer said the result of questionable editing. I would recommend this movie to my friends but with a warning that it is hard to watch. I think it might actually trigger some post traumatic stress in someone who has been abused. Please respond if you have thoughts about the last shot of the movie. Thanks
