As we approach Thanksgiving, television is already firmly entrenched in the holiday movie season: Hallmark and Lifetime have begun rolling out their dozens of cookie-cutter Christmas love stories starring city gals, country men, and interchangeable plot elements involving saving small towns or romancing royalty. What a relief, then, that Clea DuVall’s Christmas rom-com Happiest Season instantly and effortlessly breaks that mold while simultaneously being the kind of sweet, poignant, funny film you’ll want to rewatch every December.
