From The Dispatch:
While there is action and slap-stick comedy aplenty, what really makes "Up" so wonderful is its mature treatment of aging and mortality. The film tackles grown-up issues in a poignant and bittersweet way. I was reminded in some ways of Alexander Payne's "About Schmidt" in the way the film deals with getting older. It is a testament to Bob Peterson's screenplay that it balances humor and pathos with such nimble aplomb. Pixar's films have always dealt with more adult issues underneath the child friendly humor, but here it seems to go to the next level. It's not quite Pixar's deepest or best work (that title belongs to last year's "WALL-E"), but it's pretty close.Click here to read my full review.
