To use VFX or not use VFX: that is the question, and one that each TV show has to answer differently. “Sweet Tooth,” the Netflix series set in a world where a virus has wiped out much of humanity and, maybe or maybe not coincidentally, human-animal hybrids are now born, has a tactile, cobbled-together ethos in its design choices. The show’s look doesn’t just illustrate the haphazard nature of scavenging for survival but also is in itself a kind of argument for everything that makes its young human-deer hybrid Gus (Christian Convery) a hero. Building too much of that world in a digital environment would flatten it and make it feel too slick.
