There's no dialogue in this animated short , only sound effects and a musical score that's probably best described as chamber music but Matthew Hood uses the storytelling rule of " Show don't tell " so the narrative is very easy to follow: A robot is made ill because of the rats that are now inhabitating his metallic body
The animation resembles the special effects as seen in Timothy Hines notorious remake of WAR OF THE WORLDS which is safe to say is computer generated . What Hood conveys in doing very well is humanising the protagonist . Think about it , it's natural for the audience to take the side of a mammal ( Even if they are vermin ) against a non flesh and blood creation but METALSTASIS is made with enough charm to more than succeed as an animated short
