Don't forget the other 'visions' GR had for Star Trek
Another useful rule of thumb: when defending the current product requires you to trash GR as a greedy perv* in order to avoid admitting his work could have had any merit that Abrams' didn't? Probably time to stand back and reassess.
(* I mean, sure it's not exactly like he wasn't, but so what if he was? There was obviously more to Trek than that or none of us would be on this board now.)
Meh, what Roddenberry was doesn't enter into it. He was a TV producer trying to get, then keep a TV show on the air. When he realized he couldn't, he more or less abandoned it because he had to move on and make a living. He may not have been a total hedonist, but he was no visionary, either. It's fair to say he later discovered Trek could become a cash cow he could milk (that said, I would've done the same thing). It was his one great idea (and we'd all kill for one idea like that).
TOS lasted mostly because it was fun to watch and the characters were interesting. And that's all. No really deep thinking or heavy lifting was required. What mess is Kirk and the Enterprise going to get into this week and how will they get out of it?
It was more intelligent than a lot of shows in its genre because it was one of the first written for adults, but that didn't make it stand out among other just as well done shows on the networks at the time.
It was as philosophically deep and had no more or less merit than contemporaries like "Bonanza" or "Gunsmoke" or "I Spy" or "The Andy Griffith Show". Plenty of shows in the mid and late 1960s were multi-racial and tackled social issues or were little morality plays -- and some did it better than TOS did.
Today's Trek is in the "popcorn" sci-fi genre. That's where the money is. Whether that's satisfactory to everyone or not is problematic, because we're not putting up the money for the project. Whether or not the "popcorn" approach loses some fans or not is problematic, too, especially if it brings more in than it loses (which I'd bet it has). Abrams knew how to make Trek accessible to movie-going audiences today while maintaining its essence and keeping it at least recognizable to a sizeable part of the core audience. Is he a genius? Probably not. A visionary? No, but neither was Roddenberry. Did he know how to make Trek popular again? Yes.
