"The War with Grandpa is a very good comedy, which manages, among the laughter, to offer a very good definition of war. This is the good, moralizing part of the story. Everything revolves around this war."“ - Emil Calinescu - Cinemil.ro
A boy is forced to move out of his room when his recently widowed grandfather moves in.
With the help of his friends, the boy devises outrageous pranks to make his grandfather surrender the room — but he turns out to be tougher than expected and all-out war ensues.
