Have you ever wondered what makes some books, films and TV series take off, while others (often arguably better produced/ written) just do ok? The dragons certainly have. And they might well have an answer. Or at least a large chunk of one. In the second part of this two part episode, Jules and Madeleine will be looking focusing themes and sub themes in bestselling fiction - and why they're just delicious for readers/ viewers when done well. On the slab this week: Harry Potter, The Hunger Games, Twilight and many more.
