Oh no, I definitely agree with you. To tell you the truth, I prefer the way Spectacular did it. Black Kingsley is one of my favorite ideas ever (what?!), and I will say that it actually made me a bit more invested in these minor characters, who probably would not have been able to stand out all that much with the major characters had they all looked like their comic book counterparts.
That said, there is a hierarchy on what characters have iconic looks in the mythos or not. There is a clear difference between characters like Gwen Stacy and Mary Jane Watson, to characters like Debra Whitman, Sally Avril, and Liz Allan.
That said, I think Michelle is pretty much a "Detective Terri Lee". The latter being an original character from the 94 cartoon, but was basically a black Jean DeWolff... who was white in comics and Native American in Spectacular. Then again, I think Detective Lee had more in common with DeWolff than Michelle does with Mary Jane... but we'll see.
