Seasons 1 and 2 are brilliant. Seasons 3 and 4 are utterly abysmal after the departure of David Marciano. Maybe he read the upcoming scripts and ran away screaming. So my ten-star rating is only for the first half of this series. This show utterly hooked me from the start. It's such a refreshing novelty to have a hero that steadfastly follows the rules, is utterly proper and polite and is simultaneously incredibly intelligent and analytical while still being rather nieve. Being hooked on all things West Canada probably predetermined my love of this show.
