Time-travel movies usually have a clear end in sight, some situation that needs fixing. Marty McFly needs his parents to get together; John Connor needs to avoid Terminators long enough to grow up; the guys from Hot Tub Time Machine need to stop messing up the past and get back in their … hot tub time machine.
When the imperative and the ticking clock are removed, though, the time-travel power becomes a subtler narrative gimmick. About Time deploys it to tell a small, personal story — the sort where a father sits his son down in his study on the kid’s 21 birthday to tell him about a family secret. Here, it’s that both of them — all the men in their family, in fact — can travel in time. (Whether or why the women don’t inherit the same ability goes unaddressed.)
It’s a big deal, sure, but it’s not limitless. As his cheerful father (Bill Nighy) explains, Tim (Domnhall Gleeson) can Quantum Leap within his own lifetime, jumping to a moment in his past and then back to the now. Narrowing the scope and defining the stakes of the movie, Dad cautions him against using the ability for money or power — other relatives have, with inauspicious results — and instead to pursue what he truly cares about. For his dad, it’s family and good books. For the bright-eyed Tim, it’s love.
Lanky, well-meaning, but not the smoothest with women, Tim uses his ability to go back and set right what once went socially awkward. There’s a Groundhog Day-like slickness to sequences in which he tries to escape mortification with a do-over, only to muck things up a second time. With one intimidating summer crush (Margot Robbie) the chance to repeat a moment allows Tim to understand a lesson it might otherwise have taken him years to realize.
The slow growth of character and relationships is the film’s focus more than any complicated plot, but there’s complex machinery working in the background to make the time travel coherent — good thing, when multiple characters can up and play around with chronology. But the film takes few of the liberties you’d expect from its genre, and it conforms to an internal logic throughout.
