I think you've nailed an important aspect of RDM that very few people can or are willing to grasp. He did some outstanding work on DS-9, but it was under supervision by others who had a more coherent and disciplined vision of the subject.
However, when he was finally put in complete charge of a series his erratic, impulsive and narcissistic tendencies were no longer restrained and we got "stuff" like BSG and Caprica. Both series do show moments of inspired brilliance but it is more than negated by their extreme oscillations of incoherent, silly plotlines and contrived, forced emotional melodrama.
You and I are iconoclasts! I usually hear how utterly brilliant BSG is. I watched it from beginning to end, but I wondered why I was even in the audience from season three on.
