I'd agree with him on some stuff but not on others. There are a lot of deus ex machinas in Doctor Who (I have moaned many times about the amount of them in RTD's run) but I always found Moffat's episodes flowed more logically.
Maybe his quality has taken a bit of a dip now he's writing so many shows rather than just one every now and again but that was kind of expected.
I was thinking the Doctor was getting a bit god like and I think that's one reason why Moffat's had Amy and other characters saving the day sometimes. He is supposed to be a one man army still but then a few of the Timelords would be the same if they were still around wouldn't they?
And, sorry, but this is Terry Pratchett complaining about a series being ludicrous and breaking the rules of narrative?...ok.
