While discussing TNG with my brother over a couple of bowls, I figured out the source of my objection to those guys and Roddenberry's vision of the future. The fundamental problem is that they've all evolved past any interest in vice. This creates two problems. One, it makes them inherently uninteresting, particularly to a person such as myself who considers the ability to responsibly (and occasionally recklessly) engage in vice to be a healthy, redeeming quality. I don't expect them to be hedonists, the TOS guys certainly weren't, but at least some healthy interest in having a good time, which they seem to equate almost entirely to exploration. The other problem with them is that they're condescending assholes about it. They're very clear that they're better than we are and we all suck. I find that rather insulting.
They play poker with chips even though they have no concept of money. No risk, no reward. They drink whiskey and beer with no alcohol. If these guys are so advanced, then why didn't they just find a way to mitigate the problematic effects and let people catch the occasional buzz to unwind? The only time they really have any interest in getting laid for the sake of just getting laid is when they're under the "deleterious effects" of something that was completely beyond their control. Actually, Riker seems to be the one guy with a healthy interest in the ladies, which suddenly gives me a reason to like him. Even still, he's a little too virtuous about it. Ever see any fat people in the federation? With the exception of pride, do you ever see any of the 7 vices portrayed by somebody here without him being characterized as a crazy person that has to be dealt with immediately?
Really, these people are no longer human.
Coincidentally, I've just realized why Andy is so fond of the Star Trek universe. They're exactly what he strives to be.
