Your Ideal Sonic Satam Movie

I would want it to feel exactly like an old episode of SatAM without the stylistic progression or need to make sense of or introduce the characters of the current Sonic Games Universe. With the exception of Knuckles. Given the timing of Season 2's end, I tend to believe that Season 3 intended to introduce Knuckles.

Therefore, for a movie I would wish for an hour to an hour and a half that would basically sum up what the next season would have been.

The problem with that would've been the release date. Had the movie been released back in the 90's, it wouldn't have to worry about artistic changes since everyone would've been more acquainted with it. But if it were released nowadays, it would need to be altered in order to attract the current audience.

The show may have a cult fallowing, but it's small compared to the overall demographic.

True, but it seems to me that the developers would have to make a clear decision as to which demographic they are attempting to appeal to. Any attempt to cater to the current Sonic fanbase (Modern, I mean) would undermine the completely 100% different feeling which was Satam. Attempts made by Archie have at best made:

1) the transition of Modern Sonic more palatable to Satam fans
2) Satam Sonic's influence to be tolerable to modern universe Sonic. (Gradually over time it has become clear which stylistic change we are leaning toward.

All of this resulting in a completely separate feeling Sonic universe,

Of course anything made now would always feel separate from the original. It would only be, at best, a very well done homage to something precious of our childhood's. Part of this is because only the fan community could produce such a movie, which is a fact both disappointing and wholly relieving. The fact that it would be purely fan made means that it would be as catering to the Satam fanbase as only a SatAm centric fanbase would produce, and also no one would die of rage fits if it wasn't exactly what they pictured or had in mind. Because, lets face it, dear fandom at large, we all have a very clear idea in our mind's what this sort of project "should" look like, and every person's vision is unique to themselves. The fact that every fan's vision is so unique is also why a fan project should be wide sweeping and inclusive to the fan's to bring to life.
The other very important thing to keep in mind in such a production is that not every aspect of the original product was created in mind with the effect it resulted in. There is concept, there is ability --which is constrained by budget, the talent of the people within the budget or immediate availability, as well as ability as it pertains to time)--there are the changes which had to be made to the original concept due to reaction to the public, "catering" to the demographic of the times (age, time slot, advertising, ect) ---and finally there is the execution and effect it created. Basically, what I mean to say is there is always an element of "magic" involved in what any one specific creative endeavor results in. Not every aspect is creator-controlled. For example if the head animator is able to maintain the 90s style, but none of the original staff seems to be able to prevent stylistic changes from seeping in, the end result is still mostly stylized, whether that was the intent or not.

And believe me, I have a few specific thoughts on the matter of creating such a project
