Despite the execution that clearly swings towards the outrageous, the National Lampoon's Vacation series has always had this strong sense of relatability to it. Clark Griswold's constant vacation plans, no matter how big of a failure they may be, are always rooted in his strong desire to simply provide the best experience for his family. National Lampoon's Christmas Vacation follows suit, and perhaps does so in the most relatable manner in that its confined almost solely to the Griswold residence. While the antics are certainly outrageous in that National Lampoon style, consistent with the previous two films, they're not really anything that feels out of the ordinary for any household. Just about anyone can relate to wacky family members, electrical failures, and dinner that just didn't turn out right; Christmas Vacation is home to all of these and so much more. Aside from its relatability, it's also expectedly amusing: John Hughes returns to his writing duties and jams the film with tons of memorable jokes and sequences to balance out the sense of heart. Chevy Chase is once again so lovably na´ve, perfecting the deadbeat, slapstick sense of humor needed for Clark Griswold. Alongside him, Beverly D'Angelo is a warming presence amid the chaos as the always calm Ellen Griswold, and Randy Quaid's Cousin Eddie is infectiously funny as the oddball family member whose heart is certainly bigger than his brain, as Clark puts it. It serves as a directorial debut for Jeremiah Chechik, and the result is a surefire Christmas classic and another solid entry in the series.
