7. Chuck Taggart - Odyssey 5 (2002-2003)
Odyssey 5 is one of those series that I wish had found more success. The story revolves around a group of astronauts who witness the destruction of Earth. An alien observer sends their minds back in time into their physical bodies five years ago. The astronauts must attempt to prevent the disaster that will overtake Earth while continuing to live the last five years of their lives all over again. Along the way they discover that history is malleable as they attempt to right previous Earthly wrongs only to discover that when one wrong is corrected, another wrong takes its place. A great concept. Maybe it'll be remade.
