The story in Avengers vs X-men isn't that bad, Cyclops motivations were dark enough to match with past events and evreyone could see somthing like this would darken Cyclops eventually.
We all know the writers were biased because the Avengers movie made a fortune, but if you subtract the bias this has been a solid event.
Had the Avengers been less stupid, or even admit they made a few mistakes it would have been fine.
But it's not like the Marvel universe is ignoring the Avengers lack of diplomacy in this matter, Reed Richards pointed out the Avengers flaws.
I'd say this event was acceptable and even though there is some distasteful bias the event was still fun, the mutants have returned which will put X-men back in the game instead f being an island, I know there are bad things about this event but it's not going to ruin Marvel comics.
