It's yabba-dabba-two time as Fred and Barney first meet Wilma and Betty in a belated prequel to 1994's live-action original. The first half is cuter and more child-friendly, with the trademark retro gizmos including a nifty Jurassic theme park where the roller coaster comprises interlocked apatosaurus necks. By contrast, the more plot-driven second half could tax pre-adolescent patience as Fred seeks to see off competition for well-off Wilma's hand by striking it rich in Vegas. The casting is variable: The Full Monty's Mark Addy looks the part as Fred, but underplays it; as Barney, Stephen Baldwin is too gormless and two feet too tall. The girls, though, are great, with Ally McBeal's Jane Krakowski a nicely traditional Betty and Third Rock from the Sun's Kristen Johnston an unexpectedly voluptuous Wilma.

The Flintstones are at it again. The Flintstones and the Rubbles head for Rock Vegas with Fred hoping to court the lovely Wilma. Nothing will stand in the way of love, except for the conniving Chip Rockefeller who is the playboy born in Baysville but who has made it in the cutthroat town of Rock Vegas. Will Fred win Wilma's love?
