Sander put this a a reply to a post on here, I think its worth sharing as a lot of thought has gone into it, and he certainly has a point!
THE FAIRYTALE STORY ARC
501 The Eleventh Hour: Amelia Pond, name like a fairytale. Apples. Young woman goes on an adventure with her imaginary friend in her nightie, telling her not to grow up (Peter Pan).
502 The Beast Below: The Queen walks among the common folk. The beast that eats children is actually a big friendly giant.
503 Victory of the Daleks: A fake man turns human thanks to having emotions (Pinocchio).
504/5 Time of the Angels/Flesh & Stone: Amy Pond, dressed in a red hoody is chased by something evil through a forest. The Pandorica is a fairytale. River: Aren't we all?
506 Vampires of Venice: Innocent girls going into danger in a great big castle. To me it has a really big fairytale ring to it.
507 Amy's Choice: Rory's ultimate fairytale coming true is actually a dream.
508/9 The Hungry Earth/Cold Blood: People being taken to a different world. A city sleeping for a 1000 years.
510 Vincent and the Doctor: A beast, that seems evil and ugly actually has a lot of goodness in it, it is just misunderstood. (both references Vincent and the Krafayas)
511 The Lodger: An impossible love is brought together by something evil. A kiss breaks the curse.
General: Multiple sharp teeth reference. Evil wearing a disguise. What seems evil actually being good.
Remember the book art for Vincent and the Doctor that was left out due to time? Maybe that was supposed to be another fairytale reference. The Blind Fury/Krafayas being a fairytale on Gallifrey [Yes it was, pic here.] This article tidied up a little by me :)
