Query: Quality Drama Wrapped In A Sci-Fi Premise

You may never see another TV drama so well executed within a science fiction realm as Quantum Leap. Rarely can a show escape its' SF roots by telling such great stories. I liked the attention to history, which allowed so many thought-provoking ideas in each and every episode. Even the story involving Lee Harvey Oswald, despite the fact that I believe the JFK assassination issue has been down 'ad infinitum'.
