Holiday movies always make me a little nostalgic. Take “Bad Santa” (2003), where Billy Bob Thornton and Tony Cox are a felonious Kris Kringle and elfin accessory. I miss the comedic talents of the late Bernie Mac and John Ritter, who ably played supporting roles. It’s also where I first met Lauren Graham. I’m not the target demographic for “Gilmore Girls,” so witnessing her sweet flakiness as a kinky bartender was like a partially unwrapped present just for me. Memories. If you’re not smitten by her, the film’s subversively sharp writing will suffice. You’ll have a hilariously blue (language) Christmas.
