The series received a critical response from some Zelazny fans, who responded negatively to Betancourt's writing style and perceived lack of characterization, and considered his work to be fan fiction. The focus on Oberon also disappointed those who, after reading Zelazny's Merlin cycle and Amber short stories, believed that Zelazny had instead been planning another series of books to wrap up matters that he had left hanging. Zelazny's short stories, while tying up some of the loose ends, at the same time had opened doors to potential new stories going forward in the Amber universe, rather than a prequel.
