No one would call it a huge leap on the evolutionary ladder, but the animated sequel “The Croods: A New Age” is slightly funnier than its serviceable 2013 predecessor. That movie followed a family of cave persons — whose patriarch was the lunkheaded but big-hearted Grug (voiced by Nicolas Cage) — as they left the safety of the rocky alcove they called home and, thanks to the creativity of an outsider, Guy (Ryan Reynolds), embraced more innovative ways of thinking.“The Croods: A New Age,” directed by Joel Crawford, accelerates the Crood family’s clash with modernity. The clan stumbles into a verdant utopia that’s a cross between Shangri-La and Gilligan’s Island. This paradise is maintained by a family called the Bettermans, headed by Hope (Leslie Mann) and Phil (Peter Dinklage), who wear new-age garb and snobbishly show off their advanced ideas, like private rooms, windows and fruit baskets.[embedded content]They also have plans to set up Guy, who has been going steady with Eep (Emma Stone), the Croods’ eldest, with their daughter, Dawn (Kelly Marie Tran), in a subplot that the writers — perhaps because the world’s still-tiny population left them without enough characters to pair off — leave at least partly unresolved.While Dawn and Eep become besties, the dueling dads negotiate the common ground between Grug’s vestigial Cro-Magnonism and Phil’s proto-metrosexuality. Paradoxically, the movie’s energy ebbs as the proceedings turn more antic. The culture clash comedy becomes secondary once “A New Age” introduces a tribe of pugnacious, subtitled monkeys who appear to have a fairly advanced society of their own.The Croods: A New AgeRated PG.
