I enjoy originality. Quantum Leap falls into this, but works on so many levels.
First off, Scott is Sam and Dean is Al. Period. These two created their characters and it's a hoot seeing how they progress throughout the series. The two's bonding (and bantering) is a gem of the series. You'll never cease to get a chuckle from these guys. Next, the writing and storyline is so rewarding that you really get caught up in what leap will be next. Each show was unique in their own way. QL also has the ability to have you laughing one second, serious in another, and then anticipation of will Sam finish the mission. Add in some accidental history changing (we're talking time travel here) and bump-ins with historical figures and Quantum Leap shows there is no competition. Although I was disoriented and perplexed by the last show, that's only because I wish these two could have kept leaping.
