In Time is a servicable action thriller with unexpected political timeliness. The central gimmick is that everyone stops aging at 25, but that's when the clock starts ticking; they're given one year to live for free, but any life beyond that has to be earned (or given to you). Time is literally money; some wake up scrambling for enough time to get to tomorrow, and some have centuries of inherited wealth stored up.
Given the lead time involved in making a movie, the resonance with the Occupy Wall Street movement and the 1%/99% rhetoric is surely coincidental, but that doesn't stop it from occasionally feeling a bit heavy handed and clunky. Vincent Kartheiser, for instance, is saddled with a few too many speeches about how "for some to be immortal, many have to die."
Justin Timberlake can be an interesting actor in the right role, but he doesn't have quite the right charisma to be an action hero. He does have some nice moments with Amanda Seyfried, though, especially when they become the Bonnie and Clyde of time. Kartheiser gives the most interesting performance as the evil tycoon.
The movie's a perfectly nice piece of popcorn entertainment, and it will make for a pleasant afternoon in front of the TV when it gets to cable, but it's hardly something you need to rush out and see in the theater.
