I'm re-watching Seasons 1 and 2 at the moment and enjoying them even more on second viewing. Kiefer Sutherland gets an opportunity to show both sensitivity and "grit". His character was getting a bit too virtuous to be believable toward the end of Season 1 but Season 2 showed a more flawed man subjected to the emotional fall-out from Season 1 and gave Sutherland more scope to show his talent. I subscribe to Netflix but thus far only seasons 1 and 2 are available for viewing. Hoping that will change soon.
