The Staten Island Advance said the change to animation freed Napoleon from real @-@ world limitations , but thought it " lessen [ ed ] the overall appeal of the character and setting " . Lori Rackl of the Chicago Sun @-@ Times did not like the movie and liked the animated series even less ; she thought the emotions and physical humor were lost in the change to animation .
