What Roddenberry promised in terms of affordability and what he actually delivered were two different things. Those planet shows reusing existing sets and backlot locations turned out to be some of he show’s most expensive. As a producer, Roddenberry had a season of episodic TV under his belt, and a handful of failed pilots. That was the extent of his production experience, and it shows in some of the mistakes he made on Trek. A more seasoned producer wouldn’t have sent as many problematic stories to teleplay as he did without fixing their structural problems first. A lot of the eventual problems with “City,” for example, could have been fixed if Roddenberry had addressed them at the outline stage. Stories like “The Alternative Factor” or “Portrait in Black and White” could have been seriously retooled or junked before more time and money was spent on them.
