YMMV: Nanny McPhee

  • Adaptation Displacement: The movie was adapted from a series of books called Nurse Matilda, with several changes.
  • Big Lipped Alligator Moment: In the sequel, the uncle lets all the farm's piglets out of their pen and the children have to hunt them down, and Nanny McPhee decides that dragging out this task further will teach them a lesson in teamwork. Which justifies making the pigs harder to catch by granting them some speed and agility, but seriously... synchronized swimming?
  • Even Better Sequel: Nanny McPhee Returns, according to reviewers.
    • Of course YMMV on that one, considering that the sequel was considerably Lighter and Softer than its predecessor. Which could be seen as a good or a bad thing.
  • Fridge Logic:
    • In the sequel, the two boys headed to the War office in the capital to ensure they had proof that the Disappeared Dad was still alive... yet they hear the news and immediately leave empty-handed? At least grab the paper ribbon code thingy from the radio guy first...
    • The sequel's climax. Why do they have a manual explaining in detail how to diffuse an enemy bomb in plain English, and why does that bomb have a timer if it is supposed to explode on impact?
      • Fridge Brilliance: Because Nanny McPhee made it happen with her magic. It was lesson four — To Be Brave.
  • Hilarious in Hindsight: Maggie Gyllenhaal dragging someone in handcuffs may remind some of Secretary.
    • You can't help but think Nanny McPhee was inspired by Mary Poppins. Years later, Emma Thompson starred in Saving Mr. Banks, where she portrays P.L. Travers, the creator of Mary Poppins.
  • Moral Event Horizon: In the sequel, Phil's forging of the telegram.
