Time is literally money in this imaginative, futuristic film. Indeed, a hamburger could cost 30 minutes, and a gallon of gas could set you back a day.
In this have-and-have-not world, the 1% can buy immortality, while the 99% will die at 25 if they're unable to accrue additional time. It goes without saying that salaries are paid in minutes, that policemen are "time keepers" and that outlaws steal your time, and not because they're boring.
Gigantic quantities of belief suspension are needed to enjoy this flick, but the effort is worth it, probably due to Justin Timberlake's believable performance. And Amanda Seyfried's to a lesser extent.
And there's plenty of thoughtful ways to view this movie. Is endless life worth living if you're merely existing? Is immortality all it's cracked up to be? And most perplexing, since those who live beyond age 25 never appear a day older, what happens when grandma and gramps are the same age as you? Confusing, right? Come to think of it, "The Picture of Dorian Gray" was a much better film.
