L'Arroseur Arrosé is a cry from the depths of the proletariat for social emancipation, whereby the disenfranchised masses represented in a life-justifying performance as the Boy can only find justice through subversion and revolution. Indeed, the conclusion of this epic drama can been seen as a confirmation of the inherent violence in a Hegelian dialectic of class conflict; the chilling figure of the Gardener (a possible reference to ecclesiastical authority?) viciously suppresses the rights of the Boy to self-expression. The perennial nature of this conflict is undermined when both parties rush out of the "garden"; no resolution is possible except mutual annihilation.
Or, it could be a piece of light-hearted fun, as Lumiere recognised that the novelty of seeing pictures of factory workers and trains moving was wearing thin, and needed to be backed up with plot. It'll raise a smile for a few seconds, as a memento of an age with less demanding audiences.
