That said, some classic anime should never be remade. One-of-a-kind entries like Paranoia Agent (2004) and Revolutionary Girl Utena (1997) feel timeless, and the unique circumstances that helped shape these shows can never be replicated. The same goes for season one of FLCL (2000), with its eccentric, avant-garde animation style that none of the sequels have been able to recapture, regardless of thematic complexity. Although it is possible to approach these time-tested stories with a revamped perspective, that runs the risk of diluting their messaging.
