My thoughts on this series is very underwhelmed but I wanted to expand on that with how I felt about the previous series.
With the RTD-era while in hindsight it seems simplistic it's core responsibility was to re-introduce Doctor Who to a modern audience, keep the core themes of the show while re-inventing the series through serial escalation. I liked the RTD structure because it each series had a definitive beginning, mid-point, and end that tended to connect all the dots while developing the character arc of the companion for that series. Even the End of Time served as a decent movie-length good bye to this era.
Now Moffatt is a little bit more divisive for me. I like how he developed these long plot threads that last beyond multi-series and how he didn't "one and done" his companions (bringing it more in line with the Classic era) but he also tended to get VERY convoluted in his writing. There was one point where I recall something that he wrote that sounded like he retconned the RTD-era events out of the current continuity and it always felt that he had this huge ego about being showrunner and crediting himself as a far more capable DW writer than his actual execution. The 50th Anniversary stuff as well as the strong presence in (my) American culture also seemed to drive fan expectation through the roof.
A lot of fans also suffered from "companion-lag", specifically with Rose (post her return), Amy and especially Clara. Often times fans felt that the companions overtook the show often hijacking it from the Doctor completely. This is something I never really completely understood since even during the Classic era it was often Barbara and Ian (with Susan's assistance) who carried most of the narrative while the Doctor acted when it was absolutely necessary. They keep claiming that the companions "took away from time with the Doctor" but the way I saw it the Doctor has always carried himself with a bit of mystery. We would get these snippets of his darker nature and true character but often it was the companion and the characters in the arc that would go through the most changes (positive or negative). In many ways I felt Amy didn't go through growth Rory had because the show focused more on his emotions than hers so we would only get these clumps of catharsis with her character when circumstances pushed her to do so. OTHO, Clara felt like a fully developed character and each Series she was in built on her previous growth. I'm not saying every companion should go the "Clara" route but Clara's arc always felt like a more complete version of what they were trying to do with Amy (sans the romance parts).
Which brings me to my final point of the difference between Series 8, 9 and 10. I saw 8 as a return to the RTD-format since the whole "split season" format for Series 6 and 7 kind of diluted the arc structure (especially for 7 which felt like two series in one). 8 was mainly about 12 figuring out his identity, and Clara coming into her own as a character and I liked how almost every episode was a different adventure. Series 9 seemed a lot more theatrical and while the fandom still hated Clara for staying on (because she did have the best written "out" during the Christmas special) this series was a lot more focused on the Doctor. In fact Clara was pushed into the background for several episodes while we dealt with the Doctor's journeys and encounters. While it became obvious that Clara did become Rose 2.0 in a lot of ways it still felt that this was more Doctor focused.
My problem with Series 10 is that while it had a great start and some very smart writing it really doesn't engage me. For example, Class that played parallel to this show for a bit was a better watch for me because stuff kept happening each episode that made my jaw drop and despite the whinyness of some characters the showrunner seemed ballsy-er than the Torchwood writers in showing "no one was safe". I can clearly recall what happened in episodes of Class while Doctor Who just hasn't really grabbed me this year. I like Nardole, I like Bill, I like the Doctor but with Series 8 and 9 there was a lot more rewatchability there and I would get something new out of it. Series 10 just feels like it's either trying too hard or playing it safe and going through the motions with fans.
Overall I would never completely divorce myself from this show but I just wanted to give my own thoughts and opinions.
