And, of course, OMD is unquestionably the biggest example of a soft reboot at Marvel.
The aesthetics and general approach were changes Morrison was brought to do, and in part came from orders from above- the looks were a drastic change, but that was movie-mandated, and the bigger emphasis on the school was too, but it wasn't so absurd in either case. But many of the changes flowed from what happened before- he didn't ignore Magneto was the ruler of Genosha, just made him fail to protect it, wish played a part in his later characterization (not that his Magneto was good, mind you)
As for characterization of the marriage, it changed, but the point was that Scott was a very different person in part because of perhaps the biggest possible case of PTSD, by having to merge with the person he hates the most in the world, and with Jean also going through massive changes making her less human. This is, in fact, removing the elements of cosmic and super-villains, what happens in real life in many marriages- the people who were once happy go through stuff that makes them less adequate to one another, or one of them less able to relate to the other; add that to a spoiler with Emma, and, it's entirely understandable why the relationship would go the way they did. And it wasn't ignoring what happened before, it's not like Morrison had them hate each other, but just made them go through different circumstances.
