Alright, well, I just did a re-read of COLONEL SUN.
I'm not changing my stance that it's the best of the continuation novels. I find it to be a relatively quick, engaging read that builds up to a rather fantastic confrontation between Bond and Colonel Sun. Truthfully speaking, that confrontation would be the only reason COLONEL SUN would be worth adapting. It's the novel's only truly exceptional section. What I wouldn't give to hear a Bond villain say this:
"It will be my part to see to it that you undergo the worst possible pain until dawn. A delicate task, a sever challenge to my skill. And to your fortitude, Mr. Bond. Then at the proper moment I shall cause your death by a method that, as far as I know, has never been tried before. It consists, first, of breaking all twelve of the main bones of your limbs, and, secondly, of injecting you with a drug that will send you into convulsions. Perhaps you can form some sort of mental image of the agony that will be yours when your muscles pass out of control and your shattered arms and legs begin to heave and twist and thrash about of their own accord. You will be dead of shock in a few minutes."
Brutal.
Now, it's true that the rest of the book, while never dull, isn't particularly worth adapting. It's a largely low-key thriller without many memorable moments, aside from a fine location and a fight scene here or there that has some oompf. Amis' writing is largely what keeps COLONEL SUN afloat (well, that is until the climax, where the story finally becomes interesting). Well, that, and his ability to write fine travelogue (the way Amis weaves Greek history into the character backgrounds is commendable), something that no other Bond writer, save Fleming himself, managed to deliver.
Nevertheless, I would like to see EON go back to the kind of low-key spy thriller that COLONEL SUN (and most of the Flemings) offers. It's not an epic tale. I like its relative conciseness. Bring back the slight travelogue air, too.
