Star trek relies on make believe technobabble to get the plot going. You have to first goto the g-defuser compensate with intertial damping, run a diagnostic and detect tackyon particles, than state what should of been the plan from the start.
Honestly, that sounds more like TOS than what Star Trek would eventually become in later iterations. The idea of technobable really became prominent with TNG and carried forward in VOY and others.
Thing is, in the original series bible, Roddenberry stated you weren't suppose to go into how the technology works. If I remember correctly, his analogy was: "Joe Friday doesn't stop to explain how a revolver .
If you look a few pages back that is exactly what I was also advocating;that nobody cares about whether there's traces of frozen Methan in the soil of some alien planet, but can be made to care about the people who look for it.
Also "fun"....well there's "fun" and "fun" and sometimes eve "fun" Are you advocating we should make Star Trek just for the people who like to see people getting shot and girls in miniskirts? With a "quip and everybody laughs ending" no matter how many people died during the storyline?
Every incarnation of Star Trek has its humour. TNG in particular had very funny/entertaining moments, though of course it was a different kind of humour than TOS. Not everybody considers two guys throwing slurs at each other or people endlessly spurting catch phrases "fun"
As I said, I do not consider the loose rules and now risks the only problems Voy and ENT had. You are very right, the characters of those incarnations were basically bloodless.
Let alone that with those two shows they were just making Star Trek in order to make Star Trek, not because they were inspired or wanted to.
And I was never, never ever advocating Grimdark, I hate Grimdark. However there is a whole scale between "Grimdark everything is hopeless" and "Rayguns and miniskirts! Cowboyplanet Episode!"
But I think that's the problem here, the twos ides in this thread both think the other more "extreme" in their wishes than they really are.
When people hear me advocating "harder rules" for the ST universe, they think I want a purely scientific show, when nothing could be further from the truth.
When I hear people say "Star Trek needs to be fun" my mind darts to stuff like the everybody laughs ending or the Gangster planet episodes, when they might not advocating something quite that silly.
On Limiting The Technology: A story needs to have limitations to have suspense and those limitations need rules and those rules need to be consistent. They don't need to be detailed to the point that the writers need to have an engineering degree, but they need to be internally consistent. Otherwise there is no suspense. Like in Voy where people just spouted techno babble and that counted as "action" and "fun"
In the X-Men everybody knows that Rogue can't touch people, it frequently leads to complications which cause drama. Telepaths in B5 were strictly limited in their abilities from individual to individual. Spock could only read minds if he secured a persona and then performed a difficult and taxing technique.
Troi's telepathy/empathy was never clearly defined and fluctuated from episode to episode -> que the writers whining about her powers making stories impossible and her being to hard to write.
Limiting things is important and it is important that the audience knows the limits.
