There’s something very spooky about angel-memorials in graveyards. They should be reassuring, but they have exactly the opposite effect on me, even one with a beautiful face, like this one in Aston churchyard. Her wings are really like pinions too; it's quite a piece.
The fact that her arms have broken off may contribute to her spookiness.
And I can fully understand why the makers of Doctor Who should have based one of their alien-creatures, the ‘Weeping Angels’, on these statues.
