9. The Girl In The Fireplace
So say you're trying to convert your girlfriend or little sister to the show you love so dearly. It might be a bit of a hard sell to start them off with a Hartnell episode. I would definitely go with one of Tennant's episodes that has the most widespread appeal: The Girl in the Fireplace. It's got a lovely romantic storyline between the Doctor and Madame du Pompadour, and its high production values will make them forget everything they've ever heard about Doctor Who having cheap special effects. Which it does, some of the time...but best save that for when they're already hooked.
