My biggest problem with mark millar's writing is i think he trys so hard to be cutting edge and exciting that he loses track of characterisation and after effect.
when a writer wants to to focus so much on being so current or contemporary it ruins it for me, because you know when another writer comes along they will do something different anyways.
I loved the spiderman unmasking in civil war #2, then it set up the black costume and all the rest, but one more day cancelled all those stories and moments out,
and i know that millar is a big head at marvel, so i bet 100 dollars he knew the changes were going to come but his shock reveal of peter parker's identity was only a stunt, so i do have honest to god problems with his work.
it seems very pop to me, I can imagine him telling his mates he has a good idea for a story or moment and all them agreeing with him and him doing it, but when you are writer, you must write to the best of your ability and not let current trends dictate your work.
having collosus being gay in ultimate x-men is another one, you see, there is nothing in my opinion wrong with being gay in this world/life, or in a comic book, but i felt this was done for the sake of being different, but the story and character came to nothing anyways, this didn't progress any storylines or moments for collossus because ultimate x-men is/was not very remarkable anyways.
