My reviews of Pixar films tend to be rather short. Why? Because people know what they are getting. There is no studio I can think of, animation or otherwise, that has consistently delivered such great writing and high overall quality year after year. The Disney board of directors should resign and just turn their entire company over to these people.

As Usual:
Yes UP is very funny.
Yes UP is charming.
Yes UP features a script that is for kids but does not insult the intelligence of adults.
Yes, I recommend UP fully as what will likely be one of the best films of the year.
