Re: For me this summed up everything that Moffat is getting wrong
I think the problem that Moffat has suffered is the same one that plagued Babylon Five and Star Trek: DS9 back in the day. It seems like the majority of science fiction series (and franchises) at some point attempt to do the whole "encompassing story arc" thing. Unfortunately, the producers and writers get so obsessed with trying to shoehorn in oblique little references to past and future events, plot sidelines and other self-referential details that they forget to make the individual plot elements, characters and episodes within the overall story compelling in their own right.
It's like someone having the vision of some wonderful, elegant building in mind and then spending so much time, money and effort on the pretty drawings and architect's models that, by the time they come to build the thing for real, they can only afford the shoddiest of materials and the end result is a slipshod, rickety assemblage of poor quality bits and pieces.
Whereas, if they concentrated on the key individual elements first (immediate plot, character, etc.) and then built the story arc around those afterwards, they might stand a chance of coming up with something bigger, better and more compelling. Foundations first and then start building your soaring spires - not the other way around.
(And yes, of course, I realise that they have to have at least some vague idea of where they want the whole thing to go but it still feels as though too many series put the end-to-end story arc first and then forget to build it up out of good stories along the way.)
