I still don't know anything about it, not a glimpse of story, not even a bit of emotional themes, nothing besides setting.
And setting sounds damn right - dinousaurs in the era of first humans! Hell yeah!
But, wait. Dinosaurs are fully inteligent? Human is a dog-type creature? Ugh.
I don't know what to think about it. Something 'touched' me on some deep level when they called Spot like a dog. It's just...wrong to degradate human being to a dog. But well see. Hopefully it will live up to Pixars name.
