Adam Sandler tightens his embrace of broad family hijinks with this story about a set of adult twins (Sandler plays both brother and sister, yeah!) who bicker, bicker, bond, bicker some more and then bond one last time during their annual holiday gathering. The movie kicks off (and ends) with real-life twins engaged in a bit of filmed back and forth about their relationships. The off-the-cuff banter and some of the contrasting visual juxtapositions contain the real gems lacking in what gets sandwiched in between.
