I've seen all of QT's films and enjoy them. Some more than others. Like everyone I can easily think of ways this backfire.
But for a moment I'll give QT the benefit of doubt. He's a geek. He knows his genre films and knows how to mimic a period of time in his films. Jackie Brown looked like it was made in the 70's. That's more difficult than people think, it worked because he has an eye for detail. I'd love to see Trek look more like the 60's again.
So now Star Trek. ST6 famously has to change the color of Klingon blood to purple or else it would have gotten an R. So I'm guessing that's one of the limitations he's asking to have lifted, maybe he wants more realistic violence than a PG will allow. Consider a remake of "Balance of Terror" with the horrors of ship to ship combat.
I'm hoping he's not going to pepper the film with gratuitous F-bombs. That happened on Discovery and it was very out of place.
