warn represent this could spoil your movie . watch it and see if you agree . to think that we a human can not learn from the past . the futuristic society portray glamorize what hitler believe and obliterate a race of people ( in this case men ) for the benefit of society . it make me sick to my stomach . also the plausibility of a y bomb be insane . even in war our instinct for self preservation will prevent the extinction of humanity . we make mistake in the past ie represent japan and hiroshima and nagasaki in 45 but because of that we avoid a big mistake in 63 during the cuban missile crisis .
