You know exactly what you're getting in "National Lampoon's Christmas Vacation": another goofball, slapstick comedy of chaos and catastrophe with Clark Griswold (Chevy Chase) and family. This time, there's no traveling involved: Clark and Ellen (Beverly D'Angelo) prepare for a nice Christmas with the kids (played by none other than Juliette Lewis and "Roseanne" star Johnny Galecki), when their home is invaded by backwoods cousin Eddie (Randy Quaid) and his brood, along with assorted other crazy and/or stuffy relatives. Complications, of course, are inevitable. The film is preceded by "National Lampoon's Vacation" (1983) and "National Lampoon's European Vacation" (1985) and followed by "National Lampoon's Vegas Vacation" (1997). Directed by Jeremiah Chechik, who went on to do "Benny & Joon" and the Sharon Stone remake of "Diabolique". "--Jim Emerson"
