I'd rank this series so far:
1) Cold War
2) The Crimson Horror
3) The Bells of St. John
4) Journey to the Centre of the TARDIS
5) Rings of Underrated
7) Nightmare in Silver
Enjoyed 'em all though to some extent. Just odd that Mark Gatiss has kicked arse while Neil fucking Gaiman delivers the weakest offering.
Agreed. Though, I would put "Hide" closer to the top.
The Cybermen were as lame as ever. If even Neil Gaiman can't make them scary or interesting, perhaps it's time to finally retire them.
