Revelations of previously unknown siblings (99.99%
of the time),
****************************************

Was just curious as to which instance broke this rule for you?

Juggernaut and Havok.

The only stories that should never be told are those that damage the trademark.  Ex: you don't make Superman a child molester, because beyond being creepy and perverted, it ruins the Superman "brand".

Anything else can be undone if it sucks.  Bucky can be cosmic-cubed outta there.  Gwen Stacy's Goblin Babies can be a bad dream.  Bruce Wayne's crazy older brother can just never be mentioned again. 

Juggernaught and Havok are great examples.

As for stories that should NEVER be told..

Deaths of characters the writer did not create.  JB had every right to kill Guardian.  No one else does.  Comic book limbo is always the default option for not using characters.  Killing them is lazy writing.

Resurrections of characters the creator killed.  Guardian should not have been brought back.  Bucky joins this group by default.  His original death, Ski, is part of Cap's character, i.e. who he is in his Silver/Marvel Age incarnation.  Bringing back Bucky is a What If story, and should not happen in any mainstream marvel comic.  I am sure it is not an original idea either.

Puck shortness was explained properly by JB.  No problem there.  Making it something else should never have been done.

Watchmen was better than Squadron Supreme, sorry.

Dark Knight Returns and Kingdom Come were good and done right.  The minute DC started accepting them as an apocolypse of what was to come and started going there was wrong.

Crisis was an unnecessary mess.

Do you even understand "the entire concept" of
Talisman?

What I understand is that you created the first native american in comics with any true potential and let it fall into the "Revelations of previously unknown siblings (99.99%)" category by virute of a daughter that was inherently more powerful and full of enough teenage angst to overshadow her father's potential.

But Stanton, such mistakes should not be allowed to happen in the first place.  Who is running the show?  Ignoramuses?  Someone should be more responsible in the handlings of someones favorite characters.

{shrugs}  It's a creative medium (at least in theory).  Some stories work, some don't.  Some ideas work out, some don't.  It'd be nice to be able to identify with 100% certainty which are which ahead of time, such that no bad comics would ever be published, but that's just not possible.

The beauty of a lot of these characters, and a big reason they've been in print so long, is that they're darn near indestructable.  Superman as a character is FAR bigger than whatever story's being told about him in this month's issue of Action.  I enjoy seeing creators take chances with him occasionally, even if they might fail - knowing as I do that the "real" Superman will endure.
