Capaldi’s Doctor is a truly great, understated performance, but the best thing about this season so far is Clara. Moffat seems to be stepping up his game in female characters. Maybe he realized that people are less interesting when they’re just plot devices and don’t lead their own lives outside the TARDIS.
I don’t know what this story is going to be, but so far, it takes place in a military academy in a fantasy world reminiscent of the Napoleonic Wars. There are powdered wigs, pistol-swords, banter, and duels and I love it.
