See, this is where I'm of two minds. As an author, I'm repulsed by the thought that someone could someday turn one of my books into something completely different from what I'd written. But as a former screenwriter, I know I wouldn't want some author hovering over me and interfering with my ability to tell my story my way. That's why the advice commonly given to writers thinking about going to Hollywood is that unless you're in a position to have total control over an adaptation project, the best thing to do is simply take the money and run - your work is your work, and the adaptation is someone else's work, and the two don't meet in your mind.
Mind you, I've never said that Joss couldn't tell his story his way. My objection to Joss is that he lied to vulnerable people for his own gain and laughed at those people when his lies hurt them. I would only have put Ron Moore in that category if he had deliberately tried to entice the old-time
Galactica fans to watch when he knew all along that he wasn't going to give them what they wanted.
Or if he'd made Boomer a lesbian, of course...
Oh, and speaking of Gene Roddenberry, they didn't just "keep him around" for a season. He was in charge - the Great Bird of the Galaxy, the head honcho, the big cheese. Rick Berman didn't get the chance to take over until Gene's health started failing.
"The stories we tell - that's us explaining how we think the world works. Once we speak it, once we say it aloud, that makes it real for us - and real for everyone else who hears it too. When we tell a story, we invite people to visit our reality. We invite them to move in. Our stories are the reality we live in." - David Gerrold, The Martian Child
