YMMV / Maniac!

  • He Really Can Act: This was Joe Spinell's opportunity to shine as a male lead, and by god does he shine with a disturbing and poignant performance.
  • Jerkass Woobie: Yes, Frank is a misogynistic, psychotic killer... but, as you get the sense of how truly alone he is, it's hard to not feel sorry for him. Especially in the scene in the cemetery near the end.
  • Narm: As Frank is being ripped apart in the remake, he lets out a very Spongebob Squarepants-esque yell of "Augh! My leg!"
  • Nightmare Fuel:
    • The ending... having your victims suddenly come to life before you and kill you right there? Creepy, to say the least.
      • As the Cinema Snob put it: "Hehehehe, I JUST SHIT MYSELF!"
      • Want to see an even more disturbing version of the above scene? Watch the remake where you see it from the perspective from Frank himself!
    • Not to mention, Joe Spinell's performance in this is genuinely chilling.
  • Signature Scene: The "Disco Boy" having his head blown off, along with the mannequins coming to life, and dismembering Frank.
  • Tear Jerker: Frank is a walking tearjerker. He loathes murdering innocent women, but he is urged on by some voice in his head, and can barely get by on his own with his poor grasp on reality. Even sadder is the climactic scene in the cemetery, where he breaks down sobbing at Rita's grave.
