I think series 11 is really up and down. When it's good it's really good, but it's most not. I think it's too on the nose to, Dr Who has always tackled various issues, but it was done in a more subtle and nuanced way..
Pretty sure subtle and nuanced mean the same thing. So it's was super subtle.
I enjoyed the character stuff and how surprisingly good Graham is, but they lack of any real threat to the main characters bugged me. And some of the writing feels oddly disjointed when explaining stuff. The Doctor seems to jump to conclusions.
