3. Not Everything Is So Important For No Other Reason Than Drama
This one's a biggie, and it's why so many have an overabundant blind love for this era. Simply put, everything is so important and significant even though it doesn't need to be. For example, was there any reason why they built up Wilf's encounters with the Doctor to be more than a coincidence? Sure, he's the one the Doctor has to save in order to regenerate but it could have been anyone in that given situation. How many times were we told companions would 'die' but then we were given some nonsensical cop out metaphor to falsely justify it? Right down to the way the Doctor acted towards losing his companions or people dying or even the time war, everything was incredibly over-dramatic for no other reason than contrived drama. Whenever there was an emotional moment there was no sense of progression - characters would just brood about it for episodes on end and nothing would ever get done. For instance, take the loss of Rose. The Doctor spent a full 2 series pining over a companion that wasn't even that much of a loss in the grand scheme of things, seeing as he has lost much better people under worse circumstances. This can be traced right down to the reaction to his regeneration - the people who try and attempt to justify the Ten's reaction to this (there isn't a valid justification for it that isn't fabricated) clearly haven't seen episodes such as the Caves of Androzani where the Fifth Doctor went through the gates of hell and back by comparison and still came out triumphant and heroic. Compare this to Moffat's era in episodes such as a Good Man Goes to War and the ending to The Doctor's Wife where the emotional moments are executed and then moved on from like it would be ordinarily. There's no extreme amount of brooding and when there is there's a sense of the character's moving on and progressing from it. Even when Eleven lost the Ponds he did something that was akin to the way the Doctor was in the very beginning of the show, but what matters is that the character moved on from his loss and actually progressed like he should. This is something that was almost nonexistent in RTD's era - Ten's arc would go around in circles with no sense of development or resolution. His Doctor would always use to act like every instance of him losing a companion is like it happened for the first time even though he has lost so much more under much worse circumstances in other incarnations making the angst redundant and unnecessary.
2. There Is Less Style Over Substance
This is actually similar to my previous point, only a little less specific. In this one I'm talking about how obvious and aesthetic everything was - there was almost no subtlety to Ten, it was like there was an illusion of depth by giving him angst but at the same time that's all that was there. Giving a character angst does not make them deep or interesting. There was nothing nuanced or subtle about Ten or the way he was written, when he was angry he was just angry, when he was sad he was sad, when he was funny he was funny and that was it. Everything looked nice aesthetically and it fooled people into thinking there was greater depth at play than there really was. The truth is from a substantial point of view, RTD's era featured drama and characters that were for the most part was about as deep and as introspective as a soap opera or dare I say sometimes Twilight (sorry but I can compare the Doctor/Rose to Twilight until I'm blue in the face). Now, I'm not saying Moffat is perfect, I'm not saying he's always so much more deep and introspective, often his arcs and episodes come across as more of a convoluted mess. But there is substance there, there is a theme developing through his series (I won't tell you what it is because you already should know), his Doctor in the way he's portrayed is so much more nuanced and complex than people actually give the writing credit for, for example look at the colonel run away scene in a Good Man Goes to War, or the Doctor reacting to the death of the Brigadier in The Wedding of River Song, his action in the Girl Who Waited and his speech in the Rings of Akhaten to name just a few. All of these down to both Matt Smith's incredible performance and Moffat's material in those individual scenes show so much more depth and introspection than anything RTD could ever create. I'm not saying that Moffat is this amazing god of a writer or that his era is some kind of masterpiece, what I am saying is that there is substance there that people blind themselves from seeing because of their hatred.
