Both the show and its cancellation by HBO. This was truly one of the greatest shows to grace television. Season 2 solved many mysteries regarding the characters and the overall mythology but created new ones to be solved as time goes on. For those unfamiliar with the show, I almost want to suggest you don't watch it because you'll only disappoint yourself when you find out that the show received an untimely demise in what is best described as a "Canivàle Cliffhanger." However, I cannot in good conscience suggest not seeing this show, because it is one of the few and rare treasures in the world of television whose vision and storytelling was both unmistakable and uncompromising.
Fantastic show, and I already have my season 2 boxset pre-ordered.
