I think it might be near impossible to make a film about human experimentation by the Nazis and Nazi allies without seeming exploitative, as accurately they may well be represented, because the atrocities themselves were so fucking ridiculous. That said, I give this movie props for it's modest means and not coloring the Japanese as cheesy comic book villains like every Chinese movie on the subject seems to do.
Por un lado, una fuente fílmica que reconstruye sucesos historícos que como todas invitan a la reflexión y al cuestionamiento ético y moral. Por otro lado, la muestra gore que no duda en ser gráfica pero también amoral. "Men behind the sun" pasa a la historia por sus escenas macabras y por ser además una película cínica. Si bien condena este evento histórico, no duda en promover una snuff con animales.
Even though it's ruthless in it's violent demonstration, I can't say I don't love it's historical relevance and realistic perspective of human cruelty. I thought it to be pretty watchable in fact, with the exception of some very specific scenes.
This film, coupled with additional research, seems to be pretty accurate but, because of the obscurity surrounding Unit 731 and the like, I can imagine people shrugging it off as some sort of conspiracy.
