YMMV / Princess Knight

  • Adaptation Displacement: The 1966 version is much better known than original 1953 version, and reprinted much more often. This makes it a rare example where the displacement comes from the author himself.
  • Author's Saving Throw: Sapphire permanently losing her male heart in the 1966 version can be seen as an attempt by Tezuka to remove the implications that Sapphire's Action Girl status was entirely due to her having a male heart, which harms the pro-feminist message.
  • Crowning Moment of Heartwarming: In Twin Knights, after Franz, Sapphire, and Violetta have been locked in the tower by usurpers and Franz has been separated from his family, Violetta breaks down crying over what's happened. Sapphire calms her down, telling her, "You can't give in to bad people, even if things are tough". She then gets a sword off the wall and proceeds to train her daughter to improve her fencing.
  • Ending Fatigue: Generally agreed to be the main problem with the 1966 version. Three-quarters of the way in, Sapphire has gotten her kingdom back, fixed most of the conflicts, and both of the Big Bads are dead. One would assume the story ends there, but rather, Venus, a character never as much as alluded to, shows up, kidnaps Franz, and starts a completely different plot about Sapphire and Franz trying to be reunited in a completely different setting. That Venus never actually interacts with Sapphire and the only other antagonist to be faced is Sir Nylon doesn't help.
  • Fair for Its Day: The iffy gender politics are somewhat excused by the fact that it was written in The '50s. There's a definite pro-gender equality message in the story, but for modern viewers/readers it can be easy to not notice that because of all the characters going on about how men are inherently stronger than women.
  • Hilarious in Hindsight: Can be either this or Harsher in Hindsight. Whichever this manga exemplifies is up to you, but the possibility of a man's soul being within a woman's body and vice versa brings many current issues involving the LGBT community to mind.
  • Older Than They Think: Sapphire having both a boy's heart and a girl's heart is reminiscent of Two-Spirit people.
  • Unintentionally Unsympathetic: Franz comes off as a selfish jerk to a lot of modern readers, who is more interested in a girl he knows virtually nothing about than actually ruling his kingdom.
  • Values Dissonance: Modern day readers would disagree with a lot in this show, because it was made in the 1950s.
  • Viewer Gender Confusion: Sapphire for one.
  • What Do You Mean, It's Not Symbolic?: Plastic, despite being dimwitted and as pliable as his namesake, is eligible for the throne solely for being male.
