One of the things that endears me to Doctor Who so much is the way it invites its viewer fans to anticipate the story twists and hints, rather than trying to obscure them or startle you with them. It's like there's this mutual glee between the writer and the viewer, with the writer saying, "GUESS WHAT THIS IS" and the viewer saying "I KNOW I KNOW" and the writer saying back "I KNEW YOU WOULD GET IT RIGHT AWAY BECAUSE YOU ARE SO CLEVER, GO TELL YOUR FRIENDS HOW CLEVER YOU ARE, ISN'T THIS FUN," and then both writer and viewer squeeee like twelve-year-old girls at a sleepover. It matches the tone of the show and the main character in being so manic.
