Theory:Doctor Who television discontinuity and plot holes/The God Complex

Thats not ment to be taken litterally, not everything that looks like an angle becomes one, there only refering to films or pictures of an angel, after all why would making a statue of something, make it come to life?
 * Even though the Weeping Angels in this episode are fake, wouldn't they still be a threat, as "whatever has the image of an angel becomes an angel itself"?
