This "VS" issue actually brings up a good point for the whole
cancelation topic.
On one side, we have people saying that "she's not that powerful, the
writers got it wrong"; on the other side, they say, "she can do X, see
these pages". The first side says, "Doesn't matter what the pages show,
the writer was wrong, thus the pages are wrong." And so on.
The thing is, readers don't agree on how powerful Storm is. Sometimes
we think she is underwritten, like when she has trouble lifting
Wolverine with her winds and other times we think they overwrote her
when she controls "solar winds". And other people may think either one
of those events is correct.
The same goes with BP. Is the Priest interpretation correct or is the
Stan Lee/Jack Kirby interpretation correct?
But we have to remember that the writers are also readers/fans and they
have their own interpretations of past stories. One writer may say that
the previous writer got it all wrong. Or sometimes they want to
reinterpret the character or maybe better stated, turn the character
into something new. (Priest did that with BP; David did that with the
Hulk.)
But no matter the motive, readers and writers come at these books with
views on what is the right "Storm" or what is the right "BP." And since
the audience doesn't have a unified vision of these characters, it
becomes the issue for the writer to persuade enough readers that his
version is the best/right. And this automatically means, some will
think the writer "got it wrong."
From what we've seen so far, JM had his vision of BP/Storm and Doomwar
his last chance to sell the readers/audience on his version.
