Danish director Lone Scherfig skillfully adapts David Nicholls' best-selling romantic novel to the screen.

Anne Hathaway's faux British accent might be the first obvious conceit in One Day, but not its most cumbersome. That distinction belongs to the eponymous structure, a claustrophobic device that follows a pair of best friends over the course of a 22-year period, but only on many versions of July 15th.

One Day conveys a real sense of the poignancy of individual lives unfolding over time, but the film's ultimate embrace of conventionality ultimately undercuts the not inconsiderable accomplishments the project had worked so hard to achieve.

On a moment-by-moment basis, Anne Hathaway and Jim Sturgess make this long-arc love story viable, sometimes even vital. But the structural conceit proves more reductive than expansive, the big picture too overdetermined to really sweep the viewer away.

For an entry in a genre of films that frequently work as guilty pleasures even at their most formulaic, One Day doesn't offer much pleasure.
