Richard Arnold was irked by The Romulan Way and made no secret of it.
His loss. I loved the book and it fit very well in the Trek universe. Her take on the Romulans beat the hell out of how they were portrayed in later Trek.
One good thing about the way the Romulans were portrayed in later Trek is that they were portrayed so rarely--compared to the Klingons or the Cardassians, at least--that much of Duane's Rihannsu could survive into the current post-television novel continuity.
Arnold's assertion that Roddenberry was offended by the assertion in the prologue to The Romulan Way that though the Rihannsu were many things "they were never Romulans" confuses me. What there was to be offended by? Correct me if I'm wrong, but in context "they were never Romulans" meant that the Romulans were much more than inveterate enemies of the Federation, that they had a rich history and culture of their own that wasn't entirely defined by the relationship to the Federation. Right?
