Parasyte: the Maxim

Parasyte: the Maxim is one of the most intellectually serious and morally complex anime to emerge in the 2010s — an adaptation of Hitoshi Iwaaki's landmark 1990s manga that uses its body-horror premise to ask genuinely profound questions about evolution, predation, and what distinguishes humanity from the monsters it fears. When alien parasites infect humans by consuming their brains, high school student Shinichi Izumi's parasite is stopped before it reaches his head and instead bonds with his right hand — becoming Migi, a sardonic and purely rational entity with no human emotion. Their forced symbiosis forces both to confront what they are and what they owe each other. Madhouse's adaptation is elegantly produced, with action sequences of visceral physical intensity and a thoughtful, unhurried narrative pace. The philosophical conversations between Shinichi, Migi, and the host of morally ambiguous characters around them are genuinely challenging. A modern classic.
