This pleasant, lightweight live-action version of the popular cartoon is about as good as you might expect. The kids should love the broad humor and the Henson Studios creatures, but like The Addams Family movies, the look and the cast are the best things going for it. Considering that the nature of the material is so sparse, the thinly plotted story works better than other TV-to-movie fare. Our fabulous Stone Age man is promoted per a calculated move by a scheming exec (Kyle MacLachlan, whose casting ensured at least one cute guy). As a comedy, the humor is one-note and flat for anyone older than 12. The special-effects creatures look wondrous, though not as seamless as in other movies, such as in Roger Rabbit. The most joyous moments come during the full-scale re-creations of the famous credits. The Flinstones provided a major launching pad for Halle Berry as a vamping secretary. --Doug Thomas
