Dr was muddled and confused, but that happens with the regenerations.
I hope he does settle in soon. Ep 1 was choppy and disconnected.
Surprisingly, I didn’t have much trouble ‘seeing’ him as the new Doctor.
Clara seemed to have problems ‘seeing’ him as the Doctor initially, but she was accepting by the conclusion. Of course, for her, it was accept or be replaced by a new companion. :)
There was the introduction of the new character at the end with the robot.
I personally think she’s a dark manifestation of the tardis. The Garden they were in at the end seems to roughly follow the interior of the main tardis “bridge”.
