Due South is a fantastic series -one of my favorites actually. It's a drama with lots of comedy about a mounty coming to the city... Season three was probably not the best of the three/four but once you get hooked to the characters/story you have to watch it through to the end. You have to be careful when you are buying the episodes because there are two or three versions of the seasons. Some versions divide it up into only three seasons, some four, and some include the mini movie special on a separate disc and others count it as a normal episode. As long as you get the discs from the same release you should end up with every show. The last season is a bit chaotic because they thought they were being cancelled and even tore down some of the set already, also Ray is replaced with an "imposter" for most of the season (which they explain). "Ride forever" is my favorite (a two parter) but there are several outstanding episodes in there. Benton and Dieff are so easy to love, and all the supporting characters do a great job - especially ray and franchesca. The music is really well done as well. If you like Canada, Chicago, Cop dramas, or any clever fast talking comedies you should check out due south.
