This should have been the pilot.
Well, maybe that's an exaggeration.
But I definitely think the series creeators' decision to delay key revelations too long may have been what killed an otherwise intelligent and promising series.
Perfidia addressed some crucial whys and hows of the Journeyman's involuntary trips back through time.
But these important revelations came much too late. I suspect many viewers got frustrated ten episodes ago and tuned out.
A pity. Basically I liked the series. It could have been better than say, Quantum Leap, which was fun, but a little on the juvenile side.
