Without any disrespect meant to Hurst as a person, Satam was a group effort. Some critisms stem from Hurst himself not understanding the universe fully, with too much Flanderization, character demotion and suspension of disbelief utilised when he had full creative control (he DID NOT have a full understanding of Bunnie and Rotor, that's for sure).
It would be interesting to see if any other members of the original team still around would be interested in the idea, there were several writers for the show throughout it's run and surely one or two at least gained some affection for it.
This is an "interesting" angle as far as attacking Hurst for "not understanding the universe." I'm wondering where such things come from...
I just went through all of Hurst's newsgroup posts and his 2005/2006 IRC AMAs and merged them into a single document a few days ago (on my website, if anyone cares), so production stuff is fresh on my mind at the moment...
I realize that words from Hurst are likely going to be slanted in his own favor, but even before I poured through all that, on my own I found Season 1 of SatAM to be a disorganized mess, and Season 2 wasn't perfect but it definitely seemed like it had a much better idea where to go. Now, looking at Hurst's notes, he was not a major player of Season 1 -- which he said "wasn't planned at all" -- but Season 2 was pretty much completely Ben Hurst and Pat Allee. They took the best bits of the disorganized Season 1 and tried to form a cohesive Season 2. Given that SatAM really is just its own entity and didn't want to regard much of Sega's limited and ill-defined canon, then I would dare say most of the universe is invented by Hurst. So how he wouldn't understand his (mostly) own creation doesn't make any sense to me.
Of course SatAM overall is a "group effort", as obviously Hurst wasn't out there drawing cels and doing voice acting, and you had Len Janson was going to bat against Sega for them on controversial story decisions. But Ben, Pat, and Len were a machine, at least by Hurst's point of view. If any of the other writers from Season 1 really gained any affection for it, I can't say. Hurst made it sound like overall the team was pretty regularly friendly with each other and excited to work on it, but he never really seemed to mention anyone else specifically.
Again, I fully recognize that SatAM is not overall some great literary work of all humanity, and not saying it isn't without inconsistency and problems here and there, but I can definitely recognize it as a product of some creative people who fought uphill to get it as good as it got. You can really appreciate some of the battles fought by going through Hurst's own words. They had to work against DiC who insisted on this-or-that to serve their own bottom line and against Sega which of course owned the IP in the first place. SatAM was really a product of rebellion against what a lot of corporate types wanted "Sonic" to be, and that's really fascinating that way.
I guess I'm not sure what you want, but it sounds to me by what you wrote you're in favor of large retcon to support head-canon because you didn't like Hurst's ultimate direction with the show going forward. And I guess an opinion's an opinion in that respect. But I don't think there was anyone more passionate or more sure of the direction of SatAM than Hurst, so I have to give the guy a lot of respect and credit. He pretty much lived the rest of his life in regret over not getting a Season 3, and was still writing it out periodically as he was inspired even though there was no product to write for, and that's pretty hardcore fandom if there ever was any.
I guess what it really comes down to is, speaking from myself completely, I wouldn't want anything calling itself SatAM to not fully respect as much of Hurst's vision as possible. Not saying it has to follow it 100% -- especially since we don't even have a 100% unless someone gets ahold of all his personal belongings and it's documented in there somewhere -- but it should at least respect it. Because to me, what we call SatAM is Ben Hurst and his immediate crew. Anything else is derivative. (Of note, I don't consider anything Archie comics did as anything to do with SatAM. It's a vague adaption of some of SatAM at best. But those guys did not work together, and Penders even supposedly messed up one of Hurst's revival plans, so there was definitely no cooperation there.)
That's my stand on it, no one has to regard it, but just wanted to make a definitive statement on it.
