My thoughts on your posting
Nah, I'd rather have a show in the same light of Sonic CD in terms of camera work and action but with the art and storytelling of SatAM. Besides, a tv show needs a story. Why else would you watch it?
Well, for humor, for one. The perfect Sonic show wouldn't be entirely slapstick, like AoStH, but it wouldn't be overly serious like '06, either, because that direction just doesn't work for Sonic. If there had to be a story, they could reuse the basic plot from the anime movie, but change it so it'd work better as a 20-minute episode.
Tails would be in it, too, but more as a straight man (shush, it's a comedy term) to Sonic, who would be a total smart*** all the way through. (Am I allowed to say a** here?) Robotnik would act like he does here: http://www.youtube.com/watch?v=LecH7KTDGAo&feature=related
Actually, you know what? Make THIS a cartoon series, exactly like how this episode is. It's like a GOOD version of AoStH.
