I pretty much agree with the rushed ending but I wonder if the Shakri will become a returning villain. Also, I slightly saddened by the fact that the Fields of Trenzalore and the "Fall of The Eleventh" isn't being touched upon. Surely this series must have some plot behind it?
That being said, I miss the more mature plots of the Tennant era, Smith's episodes just seem too kiddie to me. He's a great Doctor but it just seems like he's going to be a child show star instead of THE Doctor.
