I wonder who his companion is going to be, that could make a difference.
I do wonder if he is old enough to have the depth of DT & CE who can not only do the quirky humour but can also convey the quite dark side of the Doctor and the essence of who he actually is (this is sounding waaaay to deep for this time of the morning lol).
I just hope it doesn't loose the whole depth of the character, being so old and knowledgeable, I just wonder if someone so young can carry it off without just seeming pretentious.
If I'm honest I'm quite glad David Morrissey didn't get it after the Christmas special as he just annoyed me in it.
