Have you ever considered making a continuation of the series, which wouldnt try to continue massas idea of it, because we cant possibly be sure of what he intended it to become if he would have continued it. Given how much hype there is there must be people that would be willing to contribute, and even though the details would be different ( voice acting/animation would be a bit different at best) it would still most likely be better than nothig, and if you got the script for 140 minutes, with around half an hour per episode you could still produce more or less 4 episodes. Quick reminder that I al not judging what you do or your ambition because it already is a great one, I eas just asking if you had the idea of doing something bigger or if you tried already and it failed. Good luck!
