As fantastic as the original movie is, there's one element of the plot that's always bothered me a little. Right at the beginning, several hundred years have already passed outside the ANSA spacecraft carrying Taylor and his crew, so if they returned to Earth, they'd be well over a thousand years out of their own time. How would they cope with such a thing? Some people have suggested their mission was to found a colony on some distant world, but if it would take so many centuries for them to reach an inhabitable world, wouldn't it be more sensible for the authorities on Earth to wait until they had developed a more efficient system that would get them across space much faster in both ship-time and Earth-time? Was it not expected that the human race would survive much longer when Taylor's crew set off?
