one would also wonder what making such a comment contributes
perhaps it allows the commenter to project their own views through the narrow aperture afforded by the author's work
maybe it lets them vent their own frustrations by judging someone's work as useless
possibly, the commenter believes that every single piece of art must have something to say; that works bereft of a clear central message or theme should not exist
what can be said about such a comment, and, indeed, any comment replying to it directly or indirectly, is that it's a waste
of everything
