Just to point out to people speculating that if the 2017 see's Capaldi leave, then it will be longer - Time of the Doctor was only a standard Christmas special length of one hour, and that had the job of throwing in some half thought out quickie explanations to supposedly explain everything in the 11th Doctor era that Moffat hadn't bothered to resolve up to that point as well as doing a leaving story.
Since he's at least been containing arcs to one series since Capaldi took over then all a Capaldi finale needs to do is tell a final story, and as such, while it could be longer than a standard Christmas special, there is no particular reason to assume it will be.

And Moffat wrapped up just enough that it worked as one complete season but he left enough threads dangling and questions unanswered that when 11, Amy and Rory got back into the Tardis at the close of the finale I felt the same excitement as I did when 10 and Rose did the very same at the end of The Christmas Invasion. And then something went awry. The most frustrating thing is that Moffat comes up with these amazing ideas and the potential for a great framework of a story arc but is too slap dash with his execution, either resorting to telling rather than showing or sometimes abandoning plot threads completely. This is what is most maddening. Every element is there if only more care had been taken. If instead of worrying more about a snappy soundbite for the trailer or a 'shock' reveal the groundwork had been done. There is an alternative version of the Amy pregnancy storyline that could have been brilliant and devastating. We didn't get it. And much as I will defend Matt Smiths last episode forever I have a great idea for how that entire concept could and should have been a season long arc that everyone (i.e no-one) would love to hear. I shall spare you but suffice to say. It's TV gold.
I think this problem of favouring twists and shocks and revelations over patient and strong story telling is an affliction that is hitting many shows, not just Doctor Who. And its not a good trend.”
I sort of symapthise with you Moffat fans in a way, because the man clearly has a big, bold imagination, and I'd guess that's what those who love his era do love about it, but for me, there's no point having an imaginative idea if you can't be bothered to seed it believably, give it time, and write it coherently, seeing it through to the end, which Moffat seemingly finds boring to do. it's just one idea out of the bag, then straight on to the next one with no thought to whether anything feels satisfyingly written.
I've always thought he's better writing single episodes than as a showrunner in charge of creating an arc. I haven't found any of his series arcs satitsfying (series 5 came close, but was ultimately tied into the mystery of the exploding TARDIS which was forgotten for years then supposedly settled with a quickie mumbled explanation) and most of the episodes in his era that I rate highly of his are Christmas specials - episodes where he's unconcerned with an arc and just writing as a single episode writer.
