These questions will not get answered. Why do viewers insist on trusting writers (Lost, Battlestar, X-Files) when its clear that some of these questions will never get answered?
That they even crop up is a sign that the plot is too convoluted to make sense. It's complex for the same of complexity, not because of the demands of the story.
Also there are no other characters so the Universe feels kind of empty and while I loved Amy Pond at the beginning she has been an inconsistent cypher the rest of the time.
I expect more of Doctor Who. Much more.
Some of the questions may not get answered. I have no problem with that. I don't need every single tiny detail wrapped in a bow. The plot was no where near convoluted and was quite easy to follow. The fact that there are still questions is a setup for later on as they made quite clear at the end of the episode itself.
I found it quite a refreshing change that this season was not overloaded with other characters. It's fun once in a while but the RTD era was overblown with millions of Daleks and Cybermen popping up multiple times. Not to mention the gathering of 7 or 8 companions at a time..some of them who just happened to pop over from a different universe! Thanks but no thanks.
If your meaning of "expecting more" is a return to the overblown cell network regenerating, switch flipping with spinning Daleks, mystical potion plots of the RTD era then I am quite happy that my expectations are different because I don't think we will be going back to that in the Moff era.
