Wu Jiang is central to all that is happening in this film, he is the heart and the hope from the start to the finish of the film. From his arrest at the start, we follow his character Wang on the train, to arriving at the compound, to the separation of men, women and children in the yard of the compound. To his new job at handing out the food to the cells, more importantly to the faith he has to find a way to escape their captures and the horrific experiments that happen below the prisoner’s cells, in the depths of the compound. We rarely see the terrible things that happen, only in a few scenes are these shown, only when it matters to the story. This I find is intentional to not take you out of the film and what it is about, but to give you the viewer hope/ faith as well. This is why I think that there are lighter comedic scenes, if it was just a gore fest of the horrors below. I for one would be turned off to watching this film. The numbers and files were destroyed by the Japanese when they retreated; there is no record to the exact numbers that they exposed to these experiments. However, 4500 files were discovered, it is estimated into millions of poor souls that were killed within this compound by the 731. This is something that we should never forget, as much as this film is just a film the time in history, did happen, human life meant nothing, as they revered to their prisoners as LOGS! What they did was barbaric and inhuman, that should never be forgotten.
