@BillRM,
The very premise of the movie is bogus but, like INDEPENDENCE DAY, it could be fun if we dispense all knowledge. Its a pretty arcane subject that only interests a few people , However, some schlub wants to market an Apocalypse, any number of people will believe them. Look at all the "teabaggers" who believe that their Medicare will be subverted.
I enjoyed UP as a really well done animated movie. It has a plot and special effects that even transcend animation skills of the Pixar folks. It was quite enjoyable and I didnt need a pile of larvae around me to watch it.
