He turned it from a utopian science ship to a naval battlecruiser in WOK.
He turned a then-serious sci-fi intellectual series into an outright contemporary comedy in VH.
He turned a idealistic view of the characters and humanity into racist, cold-war allegorys in UC. So much that members of the cast protested some of the lines they were given.
He re-wrote the series and what it was each time he went up to bat, and each time it alienated some fans because of the liberties and deviations, but each time it was met with enthusiastic approval from everyone else because finally the series was good!
