And the science in Starship Troopers is WAY more realistic than anything found in Trek.
How? Mobile suits powered by.. something. Interstellar ships driven by.. something. The good ol' Americans.. er.. Terrans vs. the monstrous, intractable bugs in a jingoistic romp across the galaxy.
BTW, I *love* Starship Troopers. And I hope to God I didn't just kill my own point...
As fantastic as some of that stuff is, it's still way more realistic than Trek. There's no wormholes teleporting you across the galaxy (made by aliens who exist at all points in time simultaneously and occasionaly spit out time manipulating artifacts for the benefit of the nearby primitive races), no talking time portals, no teleporting machines splitting one dude into a good dude and an evil dude (and then putting him back together again), no giant energy barriers that surround galaxies and occasionally turn people who try to fly through them into psionic demi-gods, no indepently developing Roman Empires on alien worlds, no big god hands grabbing starships, no all-powerful energy beings capable of disabling starships with their minds, no aliens making anyone re-enact the shootout at the OK Corral, no aliens feeding off "hate", no time travelling by flying really fast around suns, etc etc.
Yes, Trek had episodes that were science fiction and employed a lot of great sci-fi writers. But Trek also has just about every element required to label something space opera, namely:
1. Large military conflict in space
2. Outlandish science
3. Western or naval fiction influence
What makes something Space Opera, according to the dictionary, is the element of melodrama--plot and gimmicks at the expense of characterization. One thing Trek does not lack is characterization.[/quote]
Well, according to dictionary.com it's any melodrama/soap opera set in outer space. That's definitely Trek.

According to Wikipedia, it's science fiction that grows out of naval and western fiction. That article also lists Star Trek as one of its examples of the genre, along with Star Wars.

As for outlandish science, it's three centuries in the future. It's not outlandish science. What's important is that it be *consistent* science, and it generally is--certainly way the hell more consistent than TNG and especially VOY.
Again, Trek science is way more outlandish than stuff will be 300 years from now, or 3000 for that matter. We might someday gain the ability to turn a person into energy and beam him around, but that will never split you into Jeckyl and Hyde, and then rejoin you again 45 minutes later.
Im also pretty confident in my belief that there are no talking time portals to be found, no matter how hard we look.
TOS transporters were basically magic. In TNG, the Holodecks were. In DS9 the Prophets were literally a deus ex machina on occasion, and a nice juicy source of SCIENCE!
In short, I find nothing particularly consistent or realistic about Trek science. It's there to serve the story and provide plot hooks, nothing more.
If a writer has a cool plot idea about Kirk being split into a good and evil side, he doesn't care how silly it is that the transporter would do that, he waves his magic writing wand and makes it happen, because we get to learn something about Kirk (but mostly because it's cool).
