Kingdom Come was the brainchild of Ross. The only change Waid made when he scripted the issues was the removal of the preacher's family. The Kingdom, its sequel, was the brainchild of Waid. It was done despite Ross' wishes and without his input.
Kingdom Come is a work of genius and is either at or near Watchmen-level (I haven't quite decided which). The Kingdom sucked ass and made me lose faith in Waid for years.
