The Croods (2013)
I really enjoyed this Dreamworks computer animated movie about a cave family that is forced to move out of their comfort zone and the safety of their cave, and travel with a mysterious stranger to a new world.
Nicolas Cage does the voice of the father, Grug who is the family's protector and provider. He is constantly warning the family to stay in the cave, especially the young Eep (Emma Stone) who wants to get out and see more of the world.
One day she discovers an adventurous young man, Guy (Ryan Reynolds) who is traveling out to a new world. After an earthquake destroys their cave, Grug and the Crood family must follow this young man who has an entirely different outlook on life. Guy also uses some technology that is completely new to the Croods.
The movie is filled with bizarre creatures and plant life that may or may not have evolved into the present. The Croods are forced to look at things differently and re-evaluate how they've done things before.
