Quantum Leap was a TV series starring Scott Bakula as Dr. Sam Beckett, a physicist who jumped back and forth through time and reappearing in the body of someone else, righting the wrongs of their present (but always in the past).
It aired on NBC from 1989–1993 but caused a lot of frustration for its fans due to constant schedule changes and a less-than-satisfying ending. Dan Larson discussed the show’s history and touched on the sequel series that didn’t answer any questions to the mysterious actual ending.
Oh boy.
