Amy: 'She's Mrs Doctor from the future, isn't she? Is she gonna be your wife one day?'What a difference seven days makes, not to mention a change of writer. Tonight's story was a marked improvement over last week's: there were mysteries galore, dialogue to die for, and the characters actually felt real again. In short, nothing jarred, and all the main leads sparkled. After the blip that was 'Victory of the Daleks', Doctor Who feels well and truly back on track.
