Wouldn't it make more sense to ask if I'd be asking that of Thor's fans if his eye color was changed to brown? I don't know what color Thor's eyes are, I'm assuming blue...either way it seems like a relatively inconsequential change. Cyclops' beams have been portrayed as red like, 99% of the time across all media -- you can't say the same for Jean's powers being depicted pink. It's the definition of comic book fanboy/girl/other griping about something no other audience member would ever think to care about or want to change, in a medium that is not the comics.
You have not seen the show, you have no idea whether or not it'll be archaic. Jean's weak 90s TAS depiction would absolutely not fly in today's social climate and Marvel (today) seems to be the kind of company who'd take care to correct that in '97, so I'm not particularly worried. If she's constantly fainting and getting overwhelmed by her powers in '97, I'll eat my words.
Also, Jean is my favorite character...that doesn't mean I'm going to get up in arms about any AU depiction not matching the 616 comic depiction entirely. I have the 616 comics to read if I'm desperate to see Jean use pink powers.
