This sounds more like a list of "stuff I like" rather than anything recognisable as Space Opera.
It's a good list, mind.
Well, I was comparing soap and space operas.
1.Pick a show and sit down and watch any episode except the first one. How easy is it get a grasp on the characters and story? How much detail is there? Can you figure out what is going on with ONLY the information given in the episode?
So the Episode Generator gives me: Star Trek TNG The Measure of a Man. Simple enough spaceship has a robot and doctor wants to take it apart for study.
Episode Generator gives me : Battlestar Galactica Season 3 Episode 5: Collaborators. Um, yea, good luck first time watcher.
Episode Generator gives me Bablyon 5 season two The Coming of Shadows: Yea, again, good luck first time watcher.
Take any Star Wars show.....and yup, easy to follow.
Then take number of characters:
Star Trek TNG The Measure of a Man has Data, Picard, Riker, Madox and the Judge. Easy.
Both Battlestar and Bablyon 5 have enough characters to fill a room.
Star Wars show, well, they stick to the five or less.
Note how both Star Trek and Star Wars shows have the same main characters for just about the whole show.
Notice how on both Battlestar and B5 "main" characters come and go...A LOT?
Notice how in Star Trek TNG they defeat the borg by "putting them all asleep", then just crossed their fingers the borg would never, ever attack again on TV.
Notice how the resistance of B5 vs Earth took forever, even once they started engaging in combat, and slowly had to back Earth in a corner and defeat them.
Notice how in Battlestar Galactica they never found the off button to turn off all the cylons?
There are huge fundamental things here about a story. And it works just as well with books too.
