Rating: A-III (PG-13)

Routine comedy in which an airport shutdown ruins an unmarried couple’s (Vince Vaughn and Reese Witherspoon) usual Christmas getaway, forcing them instead to spend the holiday visiting each of their divorced parents (Robert Duvall, Mary Steenburgen, Sissy Spacek and Jon Voight). Despite the innovative casting of dramatic actors in comic roles, documentarian Seth Gordon’s first fictional offering, which takes many a crude detour on the way to its muted affirmation of emotional maturity and commitment, boasts a few clever exchanges between its leads, but little else. Brief nongraphic, nonmarital sexual activity, cohabitation, much sexual humor, some crude and crass language, and a contraception reference. The USCCB Office for Film & Broadcasting classification is A-III — adults. The Motion Picture Association of America rating is PG-13 — parents strongly cautioned. Some material may be inappropriate for children under 13.
