What the film conveys is pure and simple: revenge of hamburgers and fastfood, against the humans that devour them by the hour!  Elements of an action movie is evident, from the massive blasts, flying cars and slo-mo stunts.  The creators could even be cowboy flick fans.  The goryness  in some scenes can be excused, thank goodness it's animation, had it been done on real people viewers like me couldn't stand it, for sure.  Scary with a hint of  comedy, this will make you think twice the next time you order a double whooper hamburger.
