Dragon Magic Takes Hold in New 'Onward' Trailer

I know Pixar can do high concept, but this still looks odd to me. If they’re on a quest to bring back their dead dad, why have the bottom half there at all? It just looks dumb. But at least this is an original movie and not a sequel. Then again, so was The Good Dinosaur. And Pixar has another movie, Soul, coming out next year just a few months after this one (in their more reliable summer release date), so which one is the turkey?
