Just when you thought it was safe to go back to the casino, along comes the Griswold family from the popular series of National Lampoon's Vacation movies, raising a ruckus in the now family-friendly gambling capitol of the world. Clark (Chevy Chase), the bumbling Griswold patriarch, gets into his usual quota of trouble--especially on a sightseeing trip to the Hoover Dam (where puns on the word "dam" come fast, furious, and idiotic). Meanwhile, Mrs. Griswold (Beverly D'Angelo) gets to sing an ear-piercing rendition of "Lovin' You" on stage with her idol, Wayne Newton (one of the movie's comedic highlights), while son Rusty poses as a high roller and daughter Audrey trains as an exotic dancer. Randy Quaid reprises his scene-stealing role from the original Vacation movie, but let's face it--the series had already worn out its welcome, and this belated sequel earns a few good laughs but hardly qualifies as a worthy revival. Not bad as no-brainers go, but not up to par with the original film, and its better sequels like National Lampoon's Christmas Vacation. --Jeff Shannon
