"I am an idiot with a box and a screwdriver."

So after 12 weeks of soul-searching and self-scrutinisation, this is the conclusion the Doctor comes to.

Not the only disappointment, perhaps, during the two-part Series 8 finale, Dark Water and Death in Heaven.

Clara is not the Doctor, Missy is the Master (though perhaps not one worthy of the name) and Dead Danny becomes a Cyberman who saves the world. So far, so predictable.

But a Time Lord travelling by Mary Poppins' umbrella, an undead metallic Brigadier and skeletons who become Cybermen after a bout of inclement weather are a little less by-the-book.

But did Jim and Martin feel it all amounted to a satisfying end to the excellent Series 8? Or an embarrassing, drunken hurling-up after a feast of great Who?

Listen in to find out.
