Worth watching?

Absolutely. Despite its short run on television, "Journeyman" is one of the best time-travel shows that I've seen in the past decade (and that's saying something as there's always a new time-travel show every season or so on television these days). While not all of the questions that came up on the show over its single season are answered, the show ends on a great note. Definitely give it a shot; I guarantee you won't be disappointed. :)

"Never trust the future, never miss the past. If you live for the shining moment, the moment may just last."

The one season leaves nothing open-ended with the final ep neither restoring order nor leaving loose threads.

I was disappointed it ended as it would have been great to get a second season. But, it was fantastic and complete as is.
Well worth watching.
