The title of Big Bang theory is used because the story is about scientists. House of cards is used because it's a show about an empire that is fragile and will collapse. Both titles reflect something about the show. If house of cards is a show where everything goes well then it would be the equivalent of a show about sport jocks being called Big Bang theory.Are you expecting stars to begin exploding, or an extremely kinky episode at the end of Big Bang Theory?
Genuine question.
