The reason why they fail? Well, I don't know probably coincidence or probably bad marketing or could be something more drastic. Numbers didn't even reached 3000 sales units while others didn't post the numbers just to save them from embarrassment. Now I wonder if they could put those excess discs to use by offering them to public at ridiculously low price?
One thing that I could think of on boosting these figures is to add good "Specials" something that fans and viewers will surely appreciate. I just thought that why get it if you've already watched it? I know that you can have it in pure HD but other than that there's no other reason on getting one. Anyway here's the rankings.
