A villain with a reasonable goal...
Never gave this film a full-viewing until recently, I always only seemed to see it in scatterings here and there, but loved the theme song and have listened to it for years.
Plot wise, I think this is probably one of Moore's best Bond films. I actually really liked the idea of building up a secluded poppy field and then giving the heroin away for free on the streets to run the competition out of business. It's funny because it's the CIA who is the most troubled at this occurrence (because they were involved in similar schemes), with MI6 only worried about their missing/killed agents.
Out of all the Bond films, I think this was probably one of the most reasonable, smart, and tactical villains with a very achievable goal. It was neither over the top nor designed to disrupt geopolitics on a global scale like some other villainous schemes. It was also a relatively tight-knit operation, too, without a whole lot of extraneous, ridiculous, over-the-top components involved.
It's a shame Moore's Bond was portrayed as so incompetent in this film, though. He should have died like ten times and was captured one too many times for my liking. I rather liked The Man With The Golden Gun far better for the fact that other than being captured and brought to the karate school (which was kind of dumb), Bond was the one that was being the aggressor most of the time. He was written to be much better form than how he was portrayed in Live and Let Die.
But man, this film's theme song and locations were great. It's just a shame that Bond getting captured was daft enough to be parody (and probably why it was mocked to the degree it was, along with Moonraker, in the Austin Powers films).
