I know I've said it before, but the one thing that really annoys me about Michelle Jones is the same thing that annoys me about JGL in [i]Dark Knight Rises[/i].  Back when they were still trying to pass off 'John Blake' as some new mystery character, Nolan and company kept going "Oh nooo, we're [i]totally[/i] never gonna have Robin, why would we ever have Robin, nobody wants Robin, so we're never gonna do it," and then right at the end of the movie they go "Ha, he was Robin all along, we fooled you!"  They did the same thing with Zendaya, they kept saying she's a new character, and she's totally not MJ, then right at the end "Oh hahaha, she was actually MJ the whole time, we fooled you!"  That's not a trick, it's not pulling a fast one, it's just lying.

If you're gonna make a major change to a character, have the decency to commit to the bit.  Don't just lie to the audience and then pretend you're clever for doing so.  And would it kill you to at the very least dye a red streak in her hair or something to give her some slight indication as to who she's supposed to be?
