r/TopCharacterTropes post claims that it's commonly seen that the show dropped in quality during the 2010s and couldn't escape Tennant's shadow. Really?
From what I've heard, the franchise became even more popular in North America during the Smith era and the 50th Anniversary was the peak of the popularity.
Quality-wise, I haven't seen beyond Whittaker's first episode, which was solid, but considering the Moffat era dominated the 2010s with him being showrunner from 2010-2017, I find the idea that there was a decline in quality questionable.
Yes, Moffat's era had its high and lows, but so does every era. Are Series 6, 7, or 8 really that noticeable of a drop when the peak in quality people are referencing includes Series 2? I personally find Series 4 to be the only standout and 1-3 are mixed bags. 6-8 at least feel more tonally consistent. I watched Series 1's first three episodes and found them dated. Series 5 was what made me a fan and emboldened me to go through 1-4.
Many of the best episodes of RTD1 were written by Moffat. His era reduced the camp and soap opera and was more daring. Capaldi's run may have seen a ratings drop and Series 8 wasn't the best transition, but Series 9 and 10's quality cannot be understated.
