Eligible bachelors Fred Flintstone (Mark Addy) and Barney Rubble (Stephen Baldwin) have just graduated from the Bronto Crane Academy and gotten jobs at the local rock quarry. Meanwhile, heiress Wilma Slaghoople (Kristen Johnston) is miserable, as she is set to be married to Chip Rockefeller (Thomas Gibson), a rich playboy. Wilma runs away to Bedrock, where she moves in with Betty O'Shale (Jane Krakowsi). The rest, as they say, is prehistory. Fred falls for Wilma and Barney for Betty. Enter 'The Great Gazoo' (played by the great British actor Alan Cumming), the short, green alien from the original cartoons, who puts the happy couples on a BC-10 (get it?) for an exciting and romantic getaway in, you guessed it, 'Rock Vegas.' But the jilted Chip is not far behind, with a devious plan to get Wilma back.

If nothing else, The Flintstones in Viva Rock Vegas teaches us one simple fact of life-most cartoons are cartoons for a reason. This second installment and prequel to 1994's abysmal The Flintstones is an eye-catching, slapsticky and mostly vapid attempt to capitalize on the popularity of the classic TV cartoon. Try to conjure every conceivable wordplay involving rocks, stones, dinosaurs and prehistoric times and then add 10 or 20-'Isaac Mizrocki' and 'Melrock Place' are but two. Is this single joke regurgitation funny enough for 90 minutes of movie? Hardly. There are long stretches where it seems as though the screenplay pages were missing and the film just lumbers on until the next bad joke or sequence.

There are kids' movies exclusively for kids, there are kids' movies that manage to be intelligent enough to entertain the adults who bring them. Viva Rock Vegas is really just too silly for anyone. Throw in some curious (if not dubious) casting and a paper-thin script and The Flintstones in Viva Rock Vegas turns out to be much like a hunk of rock candy-sort of interesting-looking but ultimately none too fulfilling.
