Finally it starts to come together.
Well... I have been highly critical of this season so far... very few highlights in what has been a mediocre and dull build up.
But what an episode... carried entirely on the back of Capaldi who seemed to relish finally getting his chops into something meaty.
Great acting, decent writing, great directing and some nice one liners... the Tardis as a place to think reminds me of the Mind Palace from Sherlock... and I sniggered a little at that. But it was handled effectively enough.
At moments i could have sworn I actually heard Tom bakers voice such was the gravitas and finesse of the delivery... perhaps a bit of audio jiggery pokery too. Sent a little bit of a shiver down my spine when I heard it... or thought I did.
I did however think that it was spoon fed to the audience quite early on that it was the doctor leaving stuff for himself to find... scrapes of blood on the floor, shovels, clothes and the very old painting of Clara. I made the ending somewhat less than it should and could have been.
I'm not sure if one great episode makes up for all the mediocre and bad ones so far this year... and for once... I was not disappointed to see Clara for a few seconds. Knowing that she's dead soothes me and I really hope that don't pull a Ewing and he finds her in the shower in the morning... although I think they'll probably save that for the Doctor XXX porn parody.
