When upscale, happily unmarried San Francisco couple Kate and Brad find themselves socked in by fog on Christmas morning, their exotic vacation plans morph into the family-centric holiday they had, until now, gleefully avoided. Out of obligation—and unable to escape—they trudge to not one, not two, but four relative-choked festivities, increasingly mortified to find childhood fears raised, adolescent wounds reopened... and their very future together uncertain. As Brad counts the hours to when he can get away from their parents, step-parents, siblings and an assortment of nieces and nephews, Kate is starting to hear the ticking of a different kind of clock. And by the end of the day, she is beginning to wonder if their crazy families' choices are not so crazy after all.
Vince Vaughn has always killed me. He really has the best sarcasm delivery ever. This movie was no different. He had me laughing out loud numerous times and the couple finding out embarrassing things about each other through their families was great too. The only problem I had with this movie was that while it was hysterical for the first hour - it really hit a wall when it decided to get all serious and what not. I realized then that I was just enjoying the laughs and not the movie as a whole because once the laughs stopped I wasn't as in to the characters.
I'd still recommend that people go and check this one out. Its good laughs for the holiday season.
