I know that I sometimes think of seasons 1 and 2 of due South being one show, and seasons 3 and 4 as being another. I don't feel like this all of the time, of course, but there are moments.
So - what differences, apart from the Rays and some of the sets, are there between 1/2 and 3/4 due South?
I feel like the tone is often different. I would like to say that there's more emphasis on craziness, but I'm not always sure that's fair (after all, seasons 1 and 2 have episodes like "Starman" and "All The Queen's Horses".) How about a move from a straight buddy cop show to more of an ensemble?
I'm really interested how others view this, or if they completely disagree.
