I actually really liked how Xorn was handled in the run and was annoyed that subsequent writers undid all of that.
Morrison is definitely a writer to be read as incapable of laughing at his audience , rather he is someone who tries too hard to be clever (making his flaw as a writer almost identical to Gaiman’s flaw. Morrison is also vain and super narcissistic because he went to too many raves in the 90s). Still, his love of superheroes is entirely unironic and sincere (which is why both flex mentallo and all star superman are two of the best capes comics ever written)
