This fact-based romantic drama, directed by Marc Meyers, is surprisingly upbeat for most of its runtime as it charts the love story of an aspiring chef (Harry Shum Jr.) and a grad student (Jessica Rothe) whose wedding plans have to be accelerated after he is diagnosed with terminal cancer. The enthusiasm with which their friends and family rally round to save the nuptials is admirable. But viewers will be less comfortable with the couple’s casually presented choice to live together and by the seize-the-day philosophy underlying Todd Rosenberg’s script. Benignly viewed cohabitation, fleeting sexual humor, a handful of mild oaths, a few crude and crass terms. The Catholic News Service classification is A-III — adults. The Motion Picture Association rating is PG-13 — parents strongly cautioned. Some material may be inappropriate for children under 13.
