The other day, someone linked to a blog post Tom Brevoort did awhile back, and in it, Tom makes a comment that I completely agree with, and I've been meaning to post about for awhile.
To set up the quote, Tom was talking about a "Year One" Hulk Annual by John Byrne that had some changes to the Hulk's origin, including effectively changing an earlier Hulk story by Peter David.
Months later, once John had left HULK, Peter David asked to do a scene in an early issue of CAPTAIN MARVEL, a series in which Rick Jones was the co-star. In the sequence, Rick is reading a copy of this Annual and laughing his head off at how wrong they'd gotten all the facts. There was a certain satisfaction to letting Peter do that, but that was a bad call as well. There's a place and a time for such criticism, but within the stories themselves isn't it.
I absolutely agree, and I was struck by how concisely Tom put it.
I don't have a problem with creators speaking their minds about comics and other comic creators. But when they begin to take their issues with other creators into the comics themselves, I think that's crossing a line into pettiness, which is not a good thing. If a change to a character/story is so offensive, then fine, reverse the change if you think it is important enough. Just don't use your story to take shots at another creator/creators.
There's plenty of places where you can get your views across (blogs, message boards, interviews) that there should be no need for it to appear in the comics themselves.
