Theory:Doctor Who television discontinuity and plot holes/The Angels Take Manhattan


 * If the angels were strong enough to move that magnetic lock (which is described as being imposible) in Time of Angels, then why can't they break steel chains or locks on a door?
 * Okay how do they take the form of all the statues in New York? Particularly the Statue of Liberty?
 * Its stated that when they are seen, they transform into stone, in all there previous apperances, but the Statue of Liberty is made of metal.
 * What happened Grayl's guards?
 * Despite knocking Grayl over and destroying a china pot, the landing of the Tardis has no effect on anything else in the room, even the closer pieces.
 * If the Doctor can waste regeneration energy and heal others, why has he never done this before? Like with Jenny?
 * Maybe he can only do it with Time Lords? Normally, that would be a useless ability because the other Time Lord could just heal themselves (which is exactly what Jenny did, although the Doctor didn't know). But River used up her regenerations to save the Doctor.


 * How does no one notice the Statue of Liberty walking around?
 * For several minutes, no one is watching the Statue of Liberty angel, so why doesn't it get them?
