"We're going back to that style."

TV Doctor Who director Ben Wheatley's given a hilariously early interview on Capaldi and the next series of Doctor Who. Oh the discussions which will fill the void until the Autumn with this comment:

"Oh yeah, Doctor Who is pretty dark, I think. Generally it's dark, it's always been dark. Even in the more modern ones. If you look at the Tom Baker stuff, it's especially dark. When he leaves Leela — who's a very beloved assistant — he just laughs after it. There's none of the [breaking down and crying]. He just laughs, and "on to the next one," you know. It's a bonkers show. It's a monster. To have a unity that runs eight years [of the new series]… it's pretty crazy. They've done everything, they've tried all sorts of stuff. It seems to me the episodes that we're doing now seem more like classic Who. We're going back to that style. But you'll have to wait and see."

My italics. Whatever could he mean? All plot, plot, plot with character development becoming as subtle as Jo Grant's arc in the Pertwee years where she changed, became more confident but nothing was explicit? No arcs? Longer conversations?  Shot on multi-camera set-ups in the studio with obvious shifts to "film" utilising a different setting on the digital cameras?  Or just in terms of tone?  Was The Night of the Doctor a test of some sort as to a different direction for the show?  Oh the discussions, the discussions.
