Oh hang on, I just responded to all this where it was posted in the other topic. I'll copy and paste.
See, that's a quote that really gets to me. He seems arrogant and irritating.

"I must look like a vandal, a kid or an amateur… The simple fact is, all those things were planned. All of them were my choice. They’re not lazy, clumsy or desperate."
I think they probably are.
"They’re chosen. I can see more traditional ways of telling those stories, but I’m not interested."
Not capable more like.
"If you don’t like it, if you don’t join in with it then… blimey, these episodes must be nonsensical."
Something either makes sense or it doesn't. These things often don't but he throws so many things in there so that we hopefully won't notice. And sadly, it seems to work.
"But those classical structures can be seen in Primeval, in Demons, in Merlin, in all of them – and yet we stand with millions more viewers. And I think that’s partly why."
I think it's more to do with the Doctor Who name and all that comes with it (Daleks, TARDIS...), the budget and commitment behind it, and the easy publicity.
