DS9: The Musical
Ronald D. Moores idea involved a virus that would infect the crew and force them to communicate only in song. Can we do a laugh for just one episode? they fought against it and fought against it and fought against it.
STVOY: Janeway on Trial
Ronald D. Moore makes his second appearance on this list with a story that would have seen the Voyager crew mutiny and put Captain Janeway on trial. With a blended Federation/Marquis crew, Voyager had a golden opportunity to ask the question, do Starfleets ideals and values still apply when times are desperate? Janeway requiring her crew to stick by Star Fleet rules even at great personal cost, could have led to a mutiny and a great story. Moore wanted to challenge the concept of Voyager and provide Janeway actress Kate Mulgrew with the opportunity to do more with the character, but it was not to be. Moores Battlestar Galactica ran with the concept of a mutiny aboard the Galactica in Season 4 (A Disquiet Follows My Soul, The Oath, Blood on The Scales) which saw key characters take sides over the direction of the rag tag, fugitive fleet, in a great story arc and showed how much of an opportunity was missed on STVOY.
