I guess I need to see a trailer

I'm definitely all in favor of Pixar expanding their creativity with something new & refraining from more sequels but I just don't know what to think of this one. It sounds kind of odd & puzzling on paper. Or maybe I just need to read about Día de Muertos since I'm not familiar with that holiday.

Hopefully it will be up there with Inside Out & won't be another Brave.
