I'm rewatching TOS for the 1st time in years. I'm always amazed by how rough & disorganized this show looks for the 1st several episodes. The casting is all over the place with actors coming and going and characters being introduced and disappearing never to be seen again. One gets the impression of a lot of behind-the-scenes confusion and melodrama. It's even hard to figure out the proper sequence of events because of all the cast coming and going. I know "The Cage" failed as a pilot and they were forced to start over but the confusion seems to have extended well into Season 1. Does anyone know why it took Roddenberry and the other PTB so long to get it all smoothed out?
