OK, Journeyman is good, really good, and getting better with each episode. Unfortunately for the show, it's the kind of story that you have to watch from the beginning to be able follow it. Fortunately for anyone with a high-speed internet connection, NBC makes all the episodes available online. (Not a bad way to watch, by the way; there's way fewer commercials.)
What's so cool about Journeyman is the way details are added to the back story while adding plot points and complexity to the story going forward. It doesn't hurt that there are some great actors, delivering lines from clever scripts.
If you gave Journeyman a try with its maiden episode and decided it wasn't worth it, you should give it another try.
