Season Three

Roddenberry lost a grand fight to keep his time slot and realized the show simply wouldn't be seen. So he moved on, and Fred Freiberger came in to produce what would be the final season (in the process, snubbing the de facto producer, Robert Justman).

The result was a season with infrequent highs, and very deep lows. Much of it is not watchable. Enter at your own peril.
