This week’s digimated chancer is a US-Korean fossil dating from 2012 that features Melanie Griffith and William Baldwin as the voices of warring dinosaurs. Remember when these things provoked actual anticipation? This one displays early flickers of wit in zapping squabbling kids back to their hometown as it was in the Cretaceous era, before a drab quest narrative kicks in, cueing more plodding than any 70-minute should. Shameless 3D-enabling camera pirouettes and tones ranging from Sunny Delight to radioactive Haribo provide a measure of visual compensation: it’s not one for the ages, but you’ll have likely shelled out for worse.
