I'm not sure I equate adaptations and sequals as fanfiction entirely. It's not like Watchmen was made specifically to fix the ending, whereas that is the reason a lot of fanfic gets written. I see the similarities, but it's rare an author / filmaker can get away with re-writing someone else's work simply due to taste. If anything I agree with the decision: if you're going to adpat something anyway, no point in leaving in any major faults of the original.
I say rarely because you missed the most glaring example of fanfic attitudes brought to professional work: Spider Man - One More Day / Brand New Day. Quesada wasn't happy with the Spidey books, so he takes a quick cheap shortcut story to "magicaly" change or remove anything he didn't like, not just the marrage to Mary Jane. I had no problem with the concept of the story, but the way it was shoved down our throats so Joe Q could have his single Spider Man again really left me wondering if he took lessons from Fanfictiong.net.
And it certainly isn't always a disaster. Edits and changes aside, Lord of the Rings came off very well, as did Battlestar Galactica.
