"... 'Up' also generates genuine emotion and it does so by dealing unapologetically with one of Hollywood's last and most persistent taboos, old people. Instead of a Clint Eastwood-type senior citizen who is fitter than people half his age, "Up" gives us a man who uses a walker and can't handle stairs but still manages to be heroic when it counts."
What it also does, simply and poignantly, is examine the gauntlet that the old [male] must run through. And that is, regret. Even though it may based on love and emotion, this is what our hero (and widower) Carl Fredricksen (voiced wonderfully by Ed Asner) must get past in this tale--and what the villain, Charles F. Muntz (a silky voiced Christopher Plummer) cannot. Add to this what Pixar has mastered, and what Dreamworks Animation is finally catching on to, the dialog-free montage sequence. This year's model adds another great one to Pixar's pantheon that is a haunting treasure (yes, I'm an old softy, crust and all). And lastly, if you're been owned by a dog (or have cared for one at any time), you'll recognize their traits captured so lovingly with the canine supporting cast of this story. I highly recommend (because I refuse to use the obvious pun here).
