If the makers of The Flintstones had ever taken hallucinogenic drugs, then the result might have been something like DreamWorks’ prehistory-set 3D cartoon.
Certainly, directors Kirk De Micco and Chris Sanders seem to be on something, confronting their modern Stone Age family with trippy Avatar-style jungles and bizarre hybrid creatures.
Pity the creators didn’t put as much effort into the workaday story, in which teenage daughter Eep (Emma Stone) clashes with her over-protective Dad (Nicolas Cage) on a family exodus to find a new cave.
There are some chuckles - notably when Eep goes loopy over her first pair of shoes.
But for the most part it’s Neanderthal compared to the Pixar stable.
