You’re the first person I have heard that from. We’re there any plots in particular that you thought were worse (barring man with the golden gun as that was contrived and I am not sure if Fleming even truly finished it before his death)?
In Fleming's "Goldfinger", Goldfinger is actually trying to steal the gold from Fort Knox. It was much more realistic to have him instead trying to destroy the gold to increase scarcity.
Say what you want about the film "Live and Let Die" but reading Fleming trying to write "jive" was just embarrassing.
But it wasn't the plots that I thought were worse, but the writing itself.
