I'm very nearly over these non-news about things RTD might have done "if only"...
I always thought it had to be Strange New Worlds
I've struggled with SNW, and still do. One realisation made the latest season almost tolerable for me: They're not doing Star Trek, they're trying to do Doctor Who.
Say what you will about either show, but there are a lot more silly non sequitur stories in Who than Trek. The whole concept just allows for it, and that's how it should be. But the same approach doesn't work for me in Star Trek.
So yeah, Russell. It would have to be SNW because that's the Trek show that airs "Reality war" level storylines.
