Remember when the Doctor was nice? Let’s not even reach that far back: remember when he wasn’t an asshole? “The Caretaker” should be a lighthearted episode, a character-heavy look at what happens when Clara’s two worlds come crashing together. Instead, the episode’s lighter moments are weighed down by the Twelfth Doctor resuming old habits and treating Clara just as disrespectfully as the Eleventh Doctor. After weeks of promising developments (Clara’s front and center in “Deep Breath”, “Robot of Sherwood”, and “Listen”), after thoughtful, honest conversations between the Doctor and Clara and episodes that took their time, with “The Caretaker”, writers Gareth Roberts and Steven Moffat put the two right back where they were last season.
