You are right that it was the fact she was back in the costume and the poor showing in HOX 4 that sent a lot of fans over the edge (and not just Jean fans, I keep repeating it but on twitter a lot of fans thought her characterization was off or plain poor and not just die hard Jean Grey fans). If she was in the costume but still had a strong resolve or a powerful presence it wouldn't have been so controversial imo.
Still, the costume would always look wild considering she was on a space mission. It does make Jean look strange and mutant like which is why it sort of works (the mask that is).
