Gene Rodenberry was a visionary, no doubt about that. However, not every idea that he had was a good one, to pretend so is foolish. Gene wasn't a big fan of WOK from what I hear and that's widely considered to be the best Star Trek movie ever made. If we followed "Gene's vision" then DS9 would probably never have been made, and we certainly wouldn't have gotten the Dominion War. Gene never wanted significant conflicts amongst crew members, which is both boring and unrealistic. He was a great creator, but certainly not a perfect one.
