Since I'm already ripping off Carrie Vaughn's writing, I might as well rip off her blogging, too.
In the opening moments, a brief narration tells us -- essentially -- "Suspend your disbelief and just go with it." A few problems aside, I was able to do so. Viewers inclined to nit-pick will have more trouble. In terms of story, there seemed to be a lot of wasted potential. The rich guy giving the impoverished hero 100 years at the beginning felt like it should have been significant, but it's just a means to get the plot rolling. Likewise, the issue of why the hero's father died is dropped abruptly. And the premise, in general, wasn't explored as well or as deeply as I would have liked. But it was an adequate film with good performances and structure. Sci-fi that favors ideas over special effects is rare enough to be praiseworthy despite its shortcomings.
You could argue that this film is a socialist or communist fable. Maybe. It depends on whether or not you consider Robin Hood a socialist fable, since it's basically the same idea. Here before us is a corrupt society where the privileged are few and the peasants are many. In comes this heroic criminal, robbing from the rich and giving to the poor in the name of social justice. With his hot girlfriend, which I suppose gives it a bit of Bonnie and Clyde too.
Regardless of that, people who want to get some perspective on the rage over class divides in America would do well to understand the underlying metaphor here. If you, like me, grew up middle-class in the suburbs, in a family that was living the American dream, you might never get your head around the idea that on a fundamental level, money is life. Those people in Zuccotti Park railing about their poor employment prospects and huge student loans aren't really afraid of someone being more comfortable or successful than them. They're afraid of one day dying in the gutter because they can't afford a meal, or freezing to death in the cold because they couldn't pay the rent. Writers are told: show, don't tell. A thousand men and women with placards talking about their problems can get the message across, but how much more powerful is the image of a woman dropping dead in the street because she went broke?
In Time is a crappy title, BTW. I suspect the whole reason for it is because they hope to make a sequel called Out of Time. I'd watch it.
