What makes the TOS characters better is the tension between McCoy and Spock, with Kirk in the middle. He emoted, sure, but it was honest, and you ended up rooting for the guy in the end, no matter how overacted it was. Picard & Lameway, on the other hand, always have this need to try to understand and negotiate. Had Kirk encountered those fuzzy-haired guys in Voyager, he would've shot first and negotiated later. "You want technology? Here, have some....ZAP!" Case closed.
What bothers me about Enterprise is that it is supposed to be set before TOS, but the characters act like the ones in TNG, and later. Nobody seems to have any balls, except Tripp; he seems to be the brashest of the lot, which should reflect the world at that alleged time: energetic, headstrong, etc, not the "Well, let's tread cautiously and not upset the gays who might be watching..." What they need is a villain who won't negotiate, who doesn't care to "understand" earth, or Archer, or anything, and who can pretty much kick their butt. No political correctness, no niceties, no prisoners.
TOS was written at a time when the underlying political situation was that the American way is the best way: cold-war Klingons could go pound sand. Nowadays, nobody has the right to call "foul" because of multiculturalism and the misguided belief that all cultures are as valid as the next one. (Maybe an episode where everyone is invited to shore leave by the Planet of the Cannibals.....) Archer doesn't emote, except to his dog, and that makes him a sorry captain. At least Picard and Janeway got pissed every once in a while. This guy, though....yeesh.
The producers need some testosterone shots or SOMETHING.
They represented the Id, Ego and Superego.
