The plot had several interesting twists, and the movie's main concept was clever. In the characters' world, people older than 25 have only one more year to live, unless they can earn more time. As the story develops, we learn that powerful international forces have manipulated the availability and cost of the extra time the people so desperately want. In truth, there is more than enough "time"-currency to go around, but its distribution is manipulated, creating a class division in society - "have's" and "have-not's".
The metaphor for our current global banking/financial system is unmistakable and, may-I-say, brilliantly conceived.

"Thou shalt not have in thy bag diverse weights, a great and a small." (Deuteronomy 25:13)
Most of all, I liked the screenwriter's concept that time-currency was limitlessly stretchable (just as the supply of paper or electronic money is limitlessly stretchable in a fiat-banking economy). Interestingly, the message of the movie will likely resonate with socialist and conservative thinkers alike. I prefer to echo the words of Cleon Skousen, who would say that it is not about democrats and republicans, or liberals and conservatives, it is about liberty versus tyranny.
Go see the movie, and see if you agree with me.
