Happiest Season (out Nov 26) is a warm-hearted romantic comedy about a same-sex couple who visit one of their families for Christmas... except no one knows they’re a same-sex couple. It overcooks a few comedic elements but the wonderful performance of Kristen Stewart makes this a winner. She serves as the film's dramatic backbone and it allows those around her to overplay their eccentricities in search of laughs. Grade: B+.
