Well, I couldn't disagree more with those statements about the emotion in RTD episodes. Episodes like 'Turn Left', 'Utopia' "Parting of the Ways', 'Love and Monsters' etc all have heartbreaking emotion at pefectly normal volume levels.
By contrast, Moffat's characters rarely ever feel like they are anything more than gears in the great plot device. His characters all fall into the same basic templates, and he frequently just ignores even key characters, as he gets bored with them and moves on to something else.
I'm sure the lady who played Madame Kovarian was as perplexed as the rest of us, when she was continually asked back to be in episodes, yet never seemed to actually 'do' anything. She has one very brief moment of activity in 'A Good Man Goes to War' and then the final episode... she's been captured off screen.
One of the main recurring characters, and we never learn anything of any substance about her. There is the suggestion of personality at the end of 'A Good Man...' but yet again, no payoff. Because Moffat doesn't really care about character. If you're lucky, he'll keep you around long enough to have a 'Sad, emotional moment' then quickly forget about you. Most don't even get that.
(And by 'Sad, emotional moment', I of course mean another drawn out death sequence).
And quieter?! You must have a different Amy Pond to the one in my DVDs...
As for the ratings, I'm not surprised that on a Sci-Fi forum, the reaction to a more obviously Sci-Fi fans friendly version of Doctor Who is well received. But that doesn't (and cannot) take into account how the wider audience feel about the show. They as a rule, do not post in forums, and don't really think too deeply about what they feel about the show. They still watch it, but do they still love it, or really care about it that much? I would suggest that the mainstream don't ask these sorts of questions to themselves - they continue watching until... they don't.
It doesn't really get any more scientific than that. The show is on, there is usually nothing else of any quality on, they've watched it for years and so they continue to do so. But sites like Gallifrey Base have threads where people can post what their more mainstream friends/reletives/partners/kids thought of these episodes, and its been dire reading since Season 5. These people are finding the new show very hard going indeed. They don't understand it half the time, and just don't like it as much as they used to.
But for now at least, they are clinging on, just because that's how it works with mainstream viewing. You watch until you suddenly find you are no longer watching it (usually because a better show is on at the same time, or you miss a couple of weeks by accident, find you don't really miss the show and stay away). And that gradual erosion is evident in the ratings now.
The show was more inclusive under RTD. It was a Sci-Fi show yes, but it had significant crossover appeal to the mainstream. Because RTD was always careful to stress how important real human life was, and how it was just as important and valuable as adventures in time and space. Moffat doesn't have this, he has barely disguised contempt for such things, and considers adventures etc to be infinitely preferable to drab, boring, ordinary life and its sad, ordinary people.
Its a very mocking and unpleasant attitude to take, and his retreat into more hardcore sci-fi fantasy and fanwank, makes it seem like the mainstream aren't welcome on his show. RTD appealed to both mainstream and genre fans - Moffat is only interested in genre fans. It hardens the hardcore around him, but alienates everyone else.
And the fact is, I just don't think the show is as good when it takes this view. The show as others have said here, feels like a kiid's show now (though not one that many kids understand). It has lost that realistic feel that RTD was able to maintain, rooting the show in reality through constant contact with modern characters and locations, contemporary references etc. By keeping the sci-fi under control, he was able to make the show feel like it could actually happen, and so felt more real and more relevant to the viewer at home.
Nobody could mistake Moffat's version of the show for anything approaching reality. Its pulpy sci-fi fantasy comicbook stuff, and is blatantly aimed at the genre audience.
