Short answer: no.
Slightly longer answer:
I have been asked about the show quite frequently (as a FAQ would suggest), because it combines my interest in Canada with my roots (pronounced American-ly) in Chicago. But the first time I ever heard about “Due South” was in my first year of university. In England. Riddle me that.
Then my friend wrote a paper about it, and I decided to finally watch it (circa 2010), and it was AMAZING.
I am still amazed.
