I would disagree with that. I found that the Bermantrek approach fit the cast they had in TNG better than a more TOS style approach. Less sexy, sure, but sexiness is just decoration for a TV series, it's not what makes it good or bad. More talky, not compared to earlier Trek, as half of Kirk's victories came through talk. More soulless, I strongly disagree with that, other than it lacked the Spock/McCoy arguments about the merits of what defines a human. Episodes like The Defector were anything but soulless.
The big change I think is that Bermantrek focused more on the characters to drive the story as opposed to things they encounter outside the ship. You can argue the merits of this either way, but it worked a lot better with the writers they had and characters they had.
That's cool. Everybody franchise has people who like or dislike a certain thing. We have people who like the Star Wars prequels, we have people who like certain Terminator films over others, certain Doctors or companions in Doctor Who and so on.
Even though there may be people who disagree with me on this, I felt that Roddenberry 'sexy' approach was basically showing the future isn't so uptight about sex...the one reason we saw the 'man skirt' in Season 1. Of course, a few conservatives didn't like that so those 'man skirts' were gone....as were the skirt alternates for the ladies.
As the 3rd season of TNG rolled in, Star Trek became less fun. Sure, it turned up in DS9 when they actually acknowledged TOS, but Berman didn't really like TOS and it showed in his productions. Not too mention, the TOS acknowledgements were probably done on DS9 since he wasn't as hands on as he was with the other shows.
(Sidenote: Of course, they had TOS nods in ENT: Mirror Universe, Tholians, Andorians, Orions...but it was in a show that had mediocre writing. Of course, that particular show has it's fans...but not enough to keep it on the air).
I guess, for me, that's why the 2009 film was a breath of fresh air. It was a different take on a familiar series, but it was 'fun' and not talking around a table for an hour in a starship....in space...where one is supposed to be 'trekking' among the 'stars.'
Addendum: I probably mentioned it in a previous post, but Season 1 definitely has a lot of cheese and is definitely dated with certain effects and acting. And not every episode I would come back to, but there are some episodes and elements that used to have me saying: "Hmm, TNG can become my new favorite."
