i would not spoil the end and but i will talk about the ( paper thin ) plot and that why i put the spoiler alert or tag . if you haven not see the movie and but have plan to do so ( although i wouldn not recommend that a you can see by my voting ) and i would tell you not to read this beforehand . this movie be in the vain of similar torture movie ( or gorno a they be call ) . while the american business man be suppose to be a everyday man we ( or let say a western audience ) can relate to and but still stay ambiguous enough and that never fully get exploit . instead it more exploitation and in a bad way . rob a man of his sens and make it as painful a possible . but watch this be even more painful and especially because it be as predictable a it can get . while saw ( at least the first one ) have an intelligent twist to the whole thing and this movie try to disguise the whole torture thing with a social commentary and that just doesn not work . what i do not know and but read here on imdb and be the fact and that this be base on a novel . a a read this might have be more interesting and but after watch the movie and i do not feel the need for more . torture .
