Jerimiah was originally a comic book written by some one else. JMS has been burning bridges with a little tirade across the internet over his departure from Amazing Spider-Man. His Thor comic, number 7 came out a week back and it's losing it's sparkle. Though he's just began some thing called "The 12" which shows promise of TRYING to be the new Watchmen. So, he's not completely done with Marvel.
Besides captain power and the soldiers of the Future, as well as the real Ghost Busters were both excellent efforts at vision from JMS... i haven't looked at his bio in a decade
