Re:
He strikes me as a nice enough guy, but that's all. I don't know that he has any special insights into Star Trek, or his father's work in general. His comments are rather superficial.
He seems a bit tragic to me. I think he's trying to find his own place, perhaps. He's not exactly shoe-horning himself into Star Trek -- nor could he, production-wise, at this late date. His comments lead me to think that he did not really know his dad at all, because of Gene's age and health problems.
And so my sense is that he's trying to figure out who his dad was, by trying to look at his work and -- frankly -- by trying to understand the fans. We, the obsessed, may know Gene better than Rod.
And that is very sad, indeed.
