It’s so hard to tell much about how good the movie will be from trailers like this. But you can tell that the rich detail, fun characterizations, and out of the box storylines are all there. There appears to be a little “Miyazaki” in there, perhaps “Howl’s Moving Castle”.
The humor appears to be right up my alley and appealing to both adults and children. We can always count on that from Pixar because they’re making the film for themselves, essentially adult children who get to play with their toys for a living.
