Even if you haven't, your children may be enlightened by this animated family's primitive journey through times of dinosaurs and prehistoric creatures.
Though lifestyles have moved along since those basic times, the overarching theme of a father wanting to protect his family atall costs is still relevant today in our sophisticated world.
Grug (voiced by Nicolas Cage) is a simple guy - his mantra is the cave is your friend and always stick to the rules.
He allows his family out briefly during the day to catch some food, but the rules say it is then straight back to the cave and the safety it offers.
The rest of the family finds comfort in this basic life, except daughter Eep (Emma Stone), who knows there's a world out there that she wants to explore.
Eep gets her wish for adventure when their cave is destroyed and the family must seek out a new home.
The arrival of a mysterious boy - Guy (Ryan Reynolds) - scares Grug and excites Eep.
