Quantum Leap (1989-1993) and Journeyman (2007) have a lot of similarities.
Quantum Leap is about a scientist, Sam Beckett, who creates a time machine which sends his consciousness back into the bodies of different people in the past who are in a position to right the wrongs of history. Once the wrongs are righted, his consciousness leaps into the body of another person and his next mission begins. Although he does not return to his original place in the timeline, he is assisted by his business partner, Al from his time who can appear to Sam in the form of a hologram.
Journeyman is about a newspaper journalist who also jumps into the past against his will to right the wrongs of history. He will jump back to pivotal point in the life of the person who he is trying to help and then return to his present for a time before lumping back to a different point in that person’s life. Once he has changed the past and “fixed” history, he returns again to his time for a while before it starts all over again.
A couple years ago I bought all of the seasons of Quantum Leap on DVD and watched them all over again. It was interesting at first, but after a while I found the premise and the characters somewhat grating – especially the character of Al. Also there were a lot of inconsistencies with the mythology of the show that I found disappointing. I ended up selling all of the DVDs on eBay and have not missed them since.
Journeyman on the other hand is possibly one of my favorite TV shows ever. The time travel was interesting and the stories were always exciting. Which is of course why it was canceled after the first season. The biggest strength of the show is the ongoing story about the lead character, Dan Vasser and his wife, Katie and how they deal with his time traveling and the effect his absences have had on his marriage. Although it never made it to DVD, the episodes are still available on Hulu.
