Howling:The unexplained parts of "The Angels Take Manhattan"

So far as I can remember, two massive parts of the episode went completely unexplained: 94.72.194.203talk to me 19:55, September 29, 2012 (UTC)
 * How the Hell could Lady Liberty be an Angel when she's copper, pretty much hollow and was deconstructed in France then reconstructed in New York?
 * What happened to the Angel in the graveyard? Surely the Doctor didn't leave it?

Not sure about Liberty.

The Angel in the graveyard: What could the Doctor do? He can't kill it. He certainly can't take it anywhere in the TARDIS. "There's a world of time energy in there... The damage they could do could extinguish the sun." (The Doctor in Blink, possibly not word perfect but the meaning's accurate.) --89.241.77.184talk to me 22:16, September 29, 2012 (UTC)

I read it that the angels were 'taking over' so were replacing regular angels with themselves so I figured thats why it kinda sorks
