I think that, on the face of it, anthropomorphized elements are too similar to anthropomorphized emotions. So, not only does it look like a rehash of an existing idea, but the premise itself is less interesting than the original.

As someone who's literally just seen TV ads for it, it looks like a generic softball of a movie, like an off-brand Inside Out that happens to be made by the same studio. I could understand if it was cheap to make, but ouch.
