Weeping Angels and a final episode for companions are ingredients that should make for a great episode. Blink only had one of those and is probably my favorite hour of TV, ever. This episode was very lackluster except for a part near the end with Rory and Amy that was actually quite good. Shame it didn't end there, and the rest of the episode was an incoherent ball of timey wimeyness with a plot so full of holes that even the holes had holes. Yes, the statue of liberty is a weeping angel. It is a fun idea, but you got to throw that one away once you think about it.
Well, the companion is dead, long live the companion.
