With all due respect, I think the OP
Spock's Brain is conflating the phrase 'Story Arcs' with the phrase 'Serialization'.
One does not necessarily reflect the other.
'Serialization' is when a series does storylines back-to-back and carries them through an entire show. So, 26 episodes with a broader 'umbrella theme' that unfolds gradually over an entire season (or even multiple seasons) and escalates and evolves. It's a very dynamic story-telling format.
'Story Arcs' sometimes come about
in serialization, but they are not exclusive to it. A story arc is
any character driven storyline which gets revisited over many, many years. It may be as simple as recurring characters, or a developing storyline for specific people.
A story arc could be best described as anything which fundamentally changes the status quo for any given character, and which gets revisited on later occasions. Whether that's the very next episode or twenty episodes later makes no difference.
TNG's format may not have been serialized, but it had a lot of these kinds of 'character arcs'. In fact, it was this which (more than anything else) stood out so much about it at the time; that, unlike TOS, the TNG characters and the universe that they inhabit did not exist within a vacuum where everything gets wrapped up in an hour and then forgotten about. For me, that was one of the most alluring things about TNG during it's original run, that it had these kinds of story arcs.
To whit:
- Data's Search For Humanity. Beginning with the pilot (in that holodeck scene with Riker) and ending in Nemesis (with an act of noble self-sacrifice), with a great many episodes in the interim exploring the concept. Throw in any episode with Dr Soong or Lore, and take note of the fact that the emotion chip from the movies was first introduced in
the fourth season of the TV show.... and Nemesis even bookends it with Riker remembering that very first meeting with Data.
- Worf, Son of Mogh, and the Klingon Way. Start this one with Season Two's "Emissary" and carry it through with "Reunion", "Sins of the Father", "Redemption Part 1", "Redemption Part 2", and then anything involving either Alexander, the Klingon high council, or both.
- Deanna And Riker. Starting pre-series, with continuity nods towards it at many points all the way through to their recoupling in the movie 'Insurrection' and their wedding in 'Nemesis'.
- Q's Test. This is one of those interesting one that only seems obvious in hindsight. Many of Q's episodes can be summed up as "Q shows up and messes around with the crew for a bit", but when we're told in the series finale that he's been watching the characters grow and develop, it casts a shadow back across
all his appearances, and you can kind of see that, yes, his fascination with the crew does seem to be a part of something bigger. In particular compare his behaviour in "Tapestry" (where he gives Picard a second chance to see what his life would have been like without his biggest regret) to the finale (where he is trying to help Picard see 'beyond' his linear existance.) There's some deep stuff going on there.
There are many, many others.
These may not be examples of what we would call a 'story arc'
today. But nevertheless, they
ARE story arcs. In isolation they stand, but viewed culmatively they draw a much bigger picture. A story arc doesn't
necessarily need to be told in the format of a 26-episode epic storyline.
