"I personally much prefer Morrison's interpretation of Scott Summers which gives him a darker side. Not every hero needs to be a 100% virtuous scoutboy like the traditional Superman characterization used to be. Real people aren't!"

I think Morrison just picked up on some the weirdness in the Scott/Jean relationship from the Lee/Kirby and Claremont/Byrne runs. Jean, especially in the Phoenix days (I refuse the retcon) was kinky, and Scott was always angry and screwed up (abandonment issues plus his physical deformity). I've never seen Scott as having healthy sexual relationship. He needs a strong woman to dominate him even though he resents her and hates himself for it.
