YMMV / Mad Father

  • Alternate Character Interpretation: Despite the strong implication that Aya is following in her father's footsteps in the true ending, some fans choose to believe that she's simply become a kindly doctor.
  • Darkness-Induced Audience Apathy: When you learn the truth about every person in the game, including Aya given her future, it'll make you upset there's no ending where everybody dies.
  • Fanon: Various fan theories have been concocted attempting to tie Mad Father to Misao, which is set in the same universe in the future. Some of these include Ogre being Onigawara, Aya or her clone being the Library Girl, and Alfred Drevis being the Mad Scientist.
  • Moral Event Horizon: Aya's father crosses it when it's revealed he killed his wife, then crosses it again when he tries to kill Aya herself, and crosses it a third time when he tries to kill Maria.
    • It's heavily implied that Aya will go on to cross it when she gets older.
  • Narm: Some of the scares can come off as this thanks to the limited graphics.
    • Aya's character model can often fall victim to Dull Surprise and her mother's has slightly crossed eyes in some of the shots of her.
  • The Woobie: Aya and many of the Doctor's victims.
    • Although Aya arguably loses this in the True Ending, seeing as how she's become her father's successor...
