You mean bae?
I feel bad for the guy. I can empathize. You create something that creates a lot of passionate fans. Not everyone is a Star Wars fan, but hey, you weren't writing for those people anyway. You're just happy that people really like what you've created. You then take a break from it for many years, then come back with the next part of the story you want tell. Only now, a portion of those fans, and let's be honest, a minority, a very vocal minority, but still a minority, dislike your new work. You're bummed that you couldn't please everyone, but most people still really liked it, and overall, you're happy with your work. But now those dissenting opinions become angry and hateful, and they are relentless. Haters just don't ever fucking shut up. It's been 16 years and people still complain about Jar Jar. However much in the minority they are, you get sick of hearing the critics badmouth your creation. You look at doing the final part of your story, and look at the time investment and your age, you don't NEED the money, and remember the hate that you're going to get no matter how well you do, and you say "fuck it. I'm done." And you try to give the haters what they want by letting someone else finish your work.
You then watch the new finished product, and you see a story that you would not have told. You've had the ideas in your head for so long, about how this 9 part series would end up, and now you realize that you're never going to see that and you become full of regret. This was your baby, and you tried to do the right thing by giving it up, but you did it in a moment of weakness, because you were hurt, and you know that you can never take it back.
It doesn't matter how much money you have. Insults still hurt, and no one likes to have shit talked about them, especially on such a grand scale, and for so long. People are so quick to label things as "terrible, worst ever, sucks ass, abortion." It's sensationalist, and diminishes the value of true criticism, and in no way accurately reflects the quality of the work. People love jumping on the hate bandwagon though, for anything. Hate is easy. The Dark Side is a quicker path to power.
Well the haters won this time, and you got ANH 2.0. Congrats.
