Green Lantern: Mosaic sold well in its initial release, it's a well known story, and the Green Lantern franchise is popular, so why won't DC release the story as a TPB or HC?
Why is John Stewart's biggest story never referenced in the current stories? He was a freaking guardian! No other Green Lantern can say that.
Why doesn't he have his own book? Why has no DC writer developed his character since Mosaic? He is popular.
Why wouldn't DC put him on a Justice League team post-Flashpoint? He's highly associated with the team in several forms of media.
Speaking of Green Lantern: Mosaic, does DC just hate John Stewart?
In an unusual move, and although sales of the book were very strong, Green Lantern: Mosaic was cancelled early into its run. In an interview, Cully Hamner revealed the reasons behind the cancellation:
(A)s I was told at the time, it didn’t fit with DC editorial vision (whatever that means). Sales didn’t matter, fan support didn’t matter; the first issue sold about 210,000 copies and my last issue sold about 70,000, so there was plenty of support for the book. It was marked for cancellation when issue #5 came out, and they allowed Gerry Jones a year to wrap it up, but there was no doubt that it was being cancelled because somebody upstairs just didn’t care for it. So, I had a feeling after a while of creatively being against a brick wall, and got out before the end. You pay your money, you takes your chances. That’s the biz.
