Aw darn it.
Oh well, if they moved it, it should be worth the wait.
I am wondering how the story will play out though.
Normally, you need some kind of conflict to drive the story, otherwise it's just a road trip with a dinosaur instead of a car.
So, there has to be something to fight against, even if it's a natural disaster and not actual enemies.
I am wondering about the most recent concept art image of the boy though:
http://pixar.wikia.com/SpotDoes this imply that humanity never moved beyond caveman style culture?
Or that Spot is just a feral human?
That can happen for real, I know of at least one real world case where a woman lived in the rainforest without human company for most of her adult life.
And judging from the release schedule,
http://pixar.wikia.com/Inside_Out has been moved up ahead of Good Dinosaur.
Unfortunately, that's still 2015.
