I have no idea how it happened but in the middle of Doctor Who's most excruciatingly cookie-cutter season ever, we get an epic tale of international drama and espionage and it's the best thing ever. Among other things I'm a big fan of how it makes up for The Massacre by actually using the "Doctor doppelgänger" concept in an interesting way, with Salamander and the Doctor continually impersonating each other. The plot twist with Salamander's underground base is kind of ridiculous but I'm all for ridiculous plot twists in my Doctor Who.
