I wish Blizz would just give their animation team a large budget and the ability to make a full length film from any of their franchises. it'd be better than anything a live action film could ever capture. I don't know much about their script writing process or if the animation team is a major part of that, but I can tell you their directing is pretty great and I'd love to see their work at length.
Love this one as well as I love Robots and I love the philosophical questions they pose and how it seems we use them to embody the worst of our human characteristics sometimes. Or at least in cinema.
