I introduced my kids to Avatar the other day. And you know what? They loved it.
So Erika calls it the Blue Papa movie. Where the Blue Papa dies near the home tree that fell down and everyone is crying. She asked Aunty J if she could watch the Blue Papa movie and Aunty J was stumped until she went to look at the recent DVDs watched and realised she meant Avatar.
So Erika's understanding of the story is (ie what I explained)
The people with the robot clothes and flying the helicopters are bad people.
The blue people are good people
The bad people made their home tree fall down and burned it
The blue papa died and everyone cried
Then the bad people came to kill the magic tree
So everyone came to save the magic tree
