Maybe what you're saying is Trek is best left to TV. Have the four or five episodes of phaser battles and hand-wringing villains, then sneak in a more thougtful or deeper-themed episode. Like sneaking vegetables into the pizza sauce. But popular culture, where Trek belongs, is not the place to nourish your mind. You'll end up malnourished. It's a place to treat yourself to some delicious high quality junk food. Go elsewhere for your nourishment.
I appreciate that sci-fi literature is of far more merit than Star Trek, as are shows like Babylon 5 and Neon Genesis Evangelion which take a far more ideas driven approach.
But even if it has to be action/adventure, it doesn't have to be fucking stupid
action/adventure. The Trouble With Tribbles and Wrath of Khan are excellent scripts despite being adventure stories instead of science-fiction ones. Best of Both Worlds and Call to Arms are blockbuster action but smartly written. There's no excuse.
