Re: What would have improved Voyager?
^^ Straczynski faced the same problem of network interference when he was producing Crusade for TNT. After initial appeasement he grew weary of their meddling and simply refused to take their 'direction' on board. He stuck to his guns and effectively forced TNT to cancel the show. He didn't need to leave or violate his contract with them, and as such gained more kudos from B5 fandom for not allowing the direction of the show be dictated by network suits. It also hasn't prevented him from finding more work in both the television and comicbook fields.
Why couldn't Berman/Braga do the same?
Less control. They quit, UPN just hires guys to replace them who are equally if not more subservient to UPN's wishes, show likely declines in quality. Nothing is gained, and they're out of a job.
They did the best they could, under the circumstances. It's no exaggeration to say that the things I loved about VOY were their doing.
"Tell me this, do they have auditions for television?"
