The Doctor and Martha are trapped in different points of a traffic jam; it's only mildly entertaining but delivers the best Face of Boe scene, and a heartbreaking moment when the Doctor reveals he lied about Gallifrey still existing.
59. Journey To The Centre Of The TARDIS
We get to see deep inside the TARDIS, but it comes at a cost. There's a twist around corner, it's difficult to actually keep up with what's going on: but never mind, the episode totally erases itself by the end.
58. Victory Of The Daleks
A fantastic Winston Churchill, a wonderful Karen Gillan performance and Eleven coming face to face with his oldest foes will always be forgotten in favour of remembering that this, this is the episode with the Power Ranger Daleks.
57. 42
A real-time, slow-burning epic in which the Doctor is infected by the sun; this is easily Chibnall's best story, and is one of the best-paced episodes all series.
56. Rise Of The Cybermen / The Age Of Steel
A much-maligned Cybermen double-parter, it's not Tom McRae's fault that they're not from Mondas. He does the best with what he's given; it's creepy, action-packed and occasionally moving.
