MADAGASCAR
See enough movies, especially ones geared to the younger set, and you all but stop expecting to be surprised by the arc of the plot; our heroes will learn valuable Life Lessons, generally while embarking on A Perilous Journey, good will triumph over evil, the comforts of home, family, and friends will prove more beguiling than any possible adventure, yada yada yada. The joy - the shock - of the new computer-animated comedy Madagascar is that, from scene to scene, you might find yourself having no clue where events will lead, yet you're laughing too hard to pay the matter much mind.
