I adored your essay, so much. Being a huge fan of Pixar, and naturally of Up, as well, a lot of the metaphors I discovered on my own, but there are a few you pointed out that completely floored me. Especially the recurring metaphor of an empty place in one's heart. I really can't think of another film with this much attention to detail. I know Pete Docter loves to do this sort of stuff as he does the same with Inside Out. I know you posted this a while back, but again, congratulations on such a wonderful essay.
