What I do hope for...
Is a new twist when it comes to the storyline. So; putting the focus a little more back on the doctor and not so much the companion(s). It was fun, and I liked the first 'Amy Pond season' which all evolved around a weird crack in time in her bedroom.
Also I hope they will now let go of the idea to build up and re-run the whole thing in the finale of the season. It was surprising with the season mentioned above. It was nicely executed in the last season with the Silence but much less surprising because you already somewhat expected it to happen... Personally straight from the first episode when we had "2" doctors.
So I really hope they'll do something new on that part. No complaints, just a suggestion.
And I surely hope they'll let Matt Smith do what he does.. During the first episodes I kept the feeling he was trying to mimic Tennant (who I considered a very good doctor). But as the episodes progressed I have to admit he really managed to put his own 'touch' on the character.
SO; is it xmas already? ;-)
