Now that we know who will be playing the next Doctor, what do you think will change?
I feel the tone of the show will change the most drastically since the beginning of NuWho.
I suspect they will downplay the Doctors whimsical, funny nature quite a lot. He will probably be a much more brooding, no nonsense Doctor. I actually can see him as beeing pretty strict, sullen and sometimes harsh. I bet Clara will have to "work on him" for most of his first season to get him to mellow a bit.
Donīt feel this is going to be a "long" incarnation. Two seasons maybe.
