Thinking about it, I really like Peter Capaldi's Doctor in episode 1 of series 10. I can't help but feel that is shows how much Capaldi was hamstrung by Clara.
I also like his character arc how he develops. When S8 started, he was hardened and alien. When S9 started, he was still alien, but he got more affable and learned to be with humans better. In S10, he is still trying to blend in with people and fails miserably, but he has a kindness and gentleness that was missing, without a doubt the events from Clara softened him. Capaldi continues to be my doctor of the forever, they might have a new regeneration soon, but he will forever put a high bar for me.
I really wished he stayed for one more season, but there's nothing I can do about it.
