Contrasting the use of a Story Arc; that is a continuing story which needs to be told in a specific sequence with the complete in itself episode which could, virtually be shown in any order and need not “match” the previous episode.
What strikes the audience watching the latest Star Trek incarnation is that the device of an ‘alternate’ reality had to be employed.
Purists felt that some effort ought have been made to coorelate The Original Series, (TOS) with the prequel instead of copping out with a virtually brand new Star Trek.
The fact is, TOS was episodic. Different writers would use the characters in their vehicles so that there was very little ‘fact checking’ and outside of a few ‘givens‘ there was no ‘canon‘.
Deep Space Nine tried to be ’story arc’ with success. The introduction of the Dominion early in season Three would set the stage for the later incursion. This is because by the time DS9 was created the fan base was such that they had to be consistent and recognised the importance of the continuing story.
The Episodic style works with Crime dramas in which each week there’s another crime. It often doesn’t matter in what sequence one watches, because each episode is stand alone. Dr. Who is one of the few Scifi programs which can be Episodic, but most are continuing stories of persons in a future environment.
Had there been one team of writers on TOS who loved the characters, even a little, then the movie could have been fit perfectly under it, without needing the trick of ‘changing the future’ in this ‘reality.’
If this version of Star Trek results in television serialisation, one suspects there will be a team, a story arc, and many of the TOS episodes will be redone. Something perhaps to look forward to.
