So I just watched the witch episode last night, and my thoughts so far:
Jodie is a pretty enjoyable doctor, still feels like a mix between 10 and 11. Feels a bit less adept socially and more impulsive overall, although Its been a while since I saw the previous episodes, the doctor has always been been these things, just not to this extent, I would say 11 was more impulsive, 12 worse with people, but Jodie seems to have both I think, just not as bad for each compared to those 2.
During the witch episode it was so glaringly obvious that she was going to get herself accused of being a witch because she just can't tone down her doctorness for just a few moments.
Graham is great, always has cool head and comes across as very wise. I like seeing his attempt to connect with Ryan.
Ryan is pretty good as well, Seems a bit hot headed and has a drive to prove himself. I like seeing him open up to others about the troubles he has had with his mothers passing and his fathers abandonment.
Yaz is boring. I'm sorry but it often feels like shes just... there, and doesn't do a lot.
I liked it more when it was 1 or 2 companions. 3 is pushing the limit I think, feels too stretched out.
I don't think I like the new writer, Chibnal. This season feels like its missing... Something. Can't put my finger on it. Feels less magical.
I do apologize if I seem to be getting really off impressions of these episodes and characters compared to you guys, I've always been awful at analyzing story and characters and what have you. I was bad at high school english. I may also be misrembering previous seasons and doctors, and that may effect my thoughts.
