I think the concept had potential and I liked it more than Sonic X, but it didn't utilize its ideas to its fullest which was a shame.
Robotnik being a dictator and roboticizing the populace was a good way to create a situation that was everyone's problem. Everyone had something to learn from the experience and relate to each other so there was more emotional appeal to the idea. It encouraged a need for the characters to interact with others, and such a fate could happen to almost any character... in theory. It sounded like a nice loophole in getting rid of characters without actually killing them off. Especially when you compare that to things like Maria's gunshot death in SA2/Shadow the Hedgehog. The problem? Roboticization was underused, and while you had Bunnie to serve as a constant reminder, the show didn't delve much into her character, let alone any problems she could've been having. They were focused too much on characters like Sonic and Sally (and to a lesser degree, Antoine) to do a whole lot with the others. Which kind of leads me to the next issue I had with the show.
Using a princess by default was, at least in my opinion, a very shaky decision, but workable if done right. The risks involved with using royal characters like Sally however, is that their conflicts tend overlap other characters since, well ... they lead the country. If they're in a position of leadership, their decisions become more pivotal than anyone elses, and risk the plot focusing more on them than on the others. Big time if they're the strong, competent male/female types that make them all the more qualified for leadership and if they're made to be the designated gender lead if not the main character themselves.
Sally however, wasn't the lead character, and in a cartoon that had other supporting characters in it, she didn't translate well. The creatives gave her too many roles all at once. Ontop of her encompassing role as princess, she was the lead female, technical leader of the Freedom Fighters (which even Archie picked up on) AND central love interest for the show. In their desire to make a 90's pro-feminist character, they stripped the rest of the cast of any other ways to be of much importance to the team beyond generic canon fodder. It would have been one thing if Sally were say, a princess but not as competant; struggling to prove herself to everyone on the team she had a right to be there (like how Tails had been). At least Sonic or some other character could have feasibly taken the leadership position. The less roles she had tacked onto her, the better she could have been incorporated in to, but they gave her everything and then made half the cast her supporting characters to some degree so they weren't really Sonic's (or in Ant's case only a supporting character because of his feelings for Sally). This is why I probably would have rathered a character more like Amy as the princess instead.
Other problems were pointless characters that didn't need to be there like Rotor. We had Tails, I couldn't see him offer anything Uncle Chuck couldn't and he didn't have much of a bond with Sonic to begin with (unlike either of the other two aformentioned). What was the point in him again? Bunnie was more or less Sally's supporting character, although she might have been able to work in that campy 'team mom' sort of way if Sally weren't there to take that too. There could've been more action and lighthearted moments so that the show didn't come off as pretentious, and Robotnik probably could've used some of the quirks he had in the earlier issues of the comics.

I just wouldn't call it a SONIC show. :P
It probably could've been more of one, though .. if Sally wasn't as involved (or not involved at all).
That's one of my key problems, most of the cast outside Sonic and Sally are completely superfluous, it was at least a bit more subtle in the first season where there were more Day In The Limelight episodes and Sally's role was more limited, but by the second season everyone else is practically a background extra except for them and Antoine (whose overutilized and flanderized for comic relief). Even their attempts to add new additions to the cast fell flat because they had little room for plot relevance or development within all of Sonic and Sally's interaction and Antoine's goofy antics (was their any real point in introducing the Wolf Pack, even in terms of entertainment value they had near nothing interesting).
I think part of the problem came from Sally and Anotine's exagerration, they represented so many positive and negative traits respectively they made the others redundant (Rotor is tech smart but dorky and physically inept, both characters have one of those at fuller throttle, same for Bunnie's warm attitude but ditzy intelligence). Even Sonic was only that relevant as dumb muscle and Sally's love interest, other than that he was just a light Antoine, an arrogant and bumbling male foil to Sally's hypercompetence (Bunnie and Dulcy having their roles limited was practically the one thing keeping him from being superfluous in his own show).
Robotnik did gain more bumbling traits in the second season, however they were executed in a manner that made him seem kinda incompetent and ruined the suspension of disbelief that he could have ruled Mobius for over a decade with no problems.
