I am sure that it will be re-run in the States, and hope that by that time, I'll have a cable subscription and a VCR.
As for the second vs. the third season, my memory is unfortunately not as clear as I wish it were (especially re Season 2), but I can still remember to some degree a number of great shows from both of those seasons.
Season Two:
St. Sebastien's Hand
The show in which Frank finds a killing factory on a deserted (Midwestern?) farm, and determines that it is run by the Millennium Group.
The show in which either (that 'ol memory hole) the estranged Frank and Catherine are separately recruited by a millenarian, Nazi group, or Catherin is unwittingly recruited, and Frank does in to save her.
Another Nazi angle (perhaps the same story arc, in a second or third episode) in which the Nazis -- led by old Nazis -- are seeking some sort of Holy Grail artifact, the possession of which will give them control of the New Millennium.
The second season finale, with the anthrax-type plague unleashed. At the time, the show suggested that it was the end of the world. But at the beginning of the third season, we learned that it has only been released in the pacific Northwest. I'm now wondering if Carter had produced the season finale under a cloud, believing the show might now be renewed. Then, when the show was renewed, he had to re-write the outcome of the previous season.
