In my experience, ideas feel fresh when you flesh them out with interesting and unexpected information.
If you simply say that Jake was a vampire, readers will rely on their mental hoard of stereotypes to fill in the details. The result will feel flat and predictable. But if you make it clear that Jake is a high-profile political adviser to the President of the United States who wears sunglasses and black leather gloves to conceal his vampiric nature, things begin to get more interesting. Add in the fact that Jake has a human girlfriend with an adorable three-year-old daughter, and that he's being blackmailed by political adversaries of the president, and you're on your way to a fresh, new take on vampires.
