The best thing about a Tarantino Bond film is that he'd only make one. Don't get me wrong, it'd be interesting to see an R rated Bond film with great dialogue, but I think swearing, extreme violence and every character sounding kinda the same would get real boring real quick if it was the default position.

@MakeshiftPython's comments yes there was something very different about the Broccoli family and yes they did takes chances, the upside of that was some phenomenal films, the downside was more than a few suboptimal films. There desire to make the Craig era one story meant some clunky plotting, their overreliance on Purvis and Wade as if no other scriptwriter understood Bond (and yes they brought Logan and others in but P&W always seemed their default writers when something wasn't quite working) led to some poor decisions, their obvious burnout when it came to Bond and the fact that we were getting ridiculous gaps between films.
We've had nine films in the last 30 years and frankly only three of them have been classics (Goldeneye, Casino Royale, Skyfall). That's my opinion obviously, and it doesn't mean I didn't like the others, there isn't a single Bond film I completely hate, even films like Octopussy or Spectre have their moments, but I do think they should have had a better hit rate than 33.3% of films being bangers, and especially if you're going to spend 3/4/5 years between films then that new film when it shows up needs to be something special.
If you're pumping them out every two years then absolutely they can be a little rough around the edges and that's actually part of the charm, stop trying to make every film Casino Royale, sometimes we just want Tomorrow Never Dies (that's absolutely meant to be a compliment by the way!)
My fear with Amazon is that Tomorrow Never Dies is all we'll get, if that makes sense.
