I'm going by what he said and wrote. He had Jean acknowledge that she was the problem with her dying breath, then gave Cyclops new life with someone more willing to dig into his mind rather than trying to force him to talk like an adult. Also, she was unceremoniously put in the dirt because ultimately the story was about getting the author a new girlfriend, even if there was other stuff in the series that was great and more tasteful.
We should never stop talking about the Morrison run. What do people want to discuss? That time she raised
Cyclops' outside kid in the future? Onslaught? Tentacle arms? That lame black and red Phoenix variant? Zzzzzzzz
The best stuff is the juicy stuff. Gimme X-Factor and Morrison discussion on any day that ends in Y.
