This movie owes a more than a small nod to "Logan's Run". It may point the way towards a solution to the exponential population explosion that we are currently witnessing globally. Over the centuries, there have been many disasters, natural or man-made, that have culled world populations, the most recent being WWII. Disease control and health services tend to legislate against another plague and, despite the situation across the Middle-East, it seems unlikely that a catastrophic conflict will break out in the future.
The premise of "In Time" and indeed "Logan's Run" is an interesting and terrifying one. Let's hope that our so-called "governments" don't start to get ideas!
