Difficult to do this with CR being the first novel, and the first time Bond ever falls in love (until OHMSS). If EON wanted to do CR the way you wanted it, were they supposed to make this story follow on after DAD?
No, but they could still make Bond a Cold War agent in a modern world, like they did with Brosnan, then to make things closer to what Fleming intended, they should have trashed Dench. Maybe if they've done that then I wouldn't mind if Bond looks more like Red Grant than Bond himself.
And to me we see this in CR. No ordinary man can jump off cranes, jump on buses, crash through flames, survive a severe car crash or torture, win a multi-million pound card game while remaining unruffled, kill 2 huge men with swords, shoot down 4 or 5 men in Venice and destroy an entire building, remain cool and composed while bullets fly around him, etc.
You must be confused, Sweeney. I thought CR's about realism. Oh my, I think I'm also confused too...
A Bond film can be close to a novel if it follows the story as close as it can,
I see the films not based on the novels a continuation of Fleming's story, like the non-Fleming books, so how can it be closer to a novel when it's not based on any of the books?
the characters in the novel try to remain as close as they can, incidents in the novel try to remain as close as they can, the overall tone of the novel is tried to be replicated on-screen.
But we have a lady M, a Leiter who looks like Sharky from another incarnation, and a Bond who looks...

. And we have a modern setting instead of a Cold War feel.
What never happen in the books was witty, embarrassing Carry On one-liners, OTT action, silly comedy, invisible cars, underwater cars, Bond walking around all day in suits (he often wore casual, comfy outfits), double-taking pigeons, ridiculous gadgets, etc.
But James Bond killing a guy with bare hands like a thug in the bathroom, crashing through a wall and blowing up an embassy like a stupid terrorist happened in the novels? And that's what you call cool and refined?
