I'm trying to understand the reasoning behind those comments. There has always been political issues in Doctor Who as a moral lesson. It's just now more specific on American culture which might feel like they are watching the news. I mean, this is just my theory and welcome any other thoughts on that.

"...people who fell in love with the show in series 1 often really liked series 11 and I think there are some definite similarities in approach..."

That's interesting. I would not have thought of the parallels between series 1 and 11. Now it makes me think of how Yaz compares to Rose in storytelling.:)

"In that I think the characters of Graham and Ryan were developed really well, but somewhat at the expense of the Doctor and Yaz".

That is really bad that the Doctor is being undermined as a woman or should I say female? I hate to think that Yaz or the actress for that matter was brought in just as a token companion. Remember Rita from "The God Complex"? I was annoyed when she was killed off. The new writers can't stuff up another character from a particular cultural background.:(

Okay, this is beginning to sound like a rant. I should just chill and watch the show.
