Ok, I'm just going to vent my spleen about something so I'm giving fair warning.
Will people just STOP complaining about cliff hangers?!?!? A single story used to take at least two, sometimes three or four episodes. It's only because we've been conditioned to want short stories that can be given to us in a moment, thus being short on, well for want of a better word, story. I'm sorry but really annoys me, you can't have a full story with the depth that we expect from Doctor Who in 45 minutes. And don't get me started on how it was many of the same people who complained that "Curse of the Black Spot" was too short...
Aynho, I quite enjoyed that episode. What is it to be human? Is it the aggressive factory boss who thinks that anything that doesn't fit into her view of how things should be is a threat? Is it the girl running around scared and confused? Is it the same girl (and yet not the same) trying to come to terms with the fact that all her memories were lived by someone else, who was her and yet not her? Is it the man who goes off, despite his fear, to help someone he doesn't know? And next week! What is it to be a Time Lord?
