Safety Not Guaranteed (15) 85 mins **
Eight years ago, Sundance premiered Shane Carruth’s coolly conceptual time-travel drama Primer; here’s the kooky romcom derivative, dotted with Star Wars nods and “wacky” training montages. Parks and Rec’s Aubrey Plaza plays a Seattle magazine intern investigating a small-town shelfstacker (Mark Duplass) who’s planned a trip back to 2001; the film dithers over how mentally troubled this individual is, until its geek-pandering finale. Plaza’s abrasive comic gifts are largely wasted amid the cutesiness, though New Girl’s Jake Johnson has a nice supporting turn as a blunt journo, nudging his charges away from his own past mistakes.
Safety Not Guaranteed opens in selected cinemas from Boxing Day.
