This was the favorite show of my best friend in "high school," I even remember he dressed as Walker for Halloween one year.
Personally, I never really invested in the show all that much - I've seen the odd episode here and there, but it's not a show that I went out of my way to see.
I recently learned something ironic: one of the co-creators of Walker was also previously one of the co-creators of HOGAN'S HEROES - now you talk about two completely different shows! Matter of fact, I think that same person was even the producer of THE GODFATHER.
