Here's the rundown:
Thunderball (1965): I'd remembered this one being boring, but it was not boring. Domino is pretty useless, but hell, James has got a jet pack! That flies! How do you improve on that?
You Only Live Twice (1967): Seriously, where do they get this stuff? Kissy Suzuki? Mini-helicopter battles? A volcanic crater with a false bottom that opens to reveal a monorail-equipped underground lair/launching pad for a "carnivorous space craft" that eats your astronauts for lunch? The death of his randomly Chinese girlfriend (the setting-theme is Japan, so why she's Chinese I could never figure out), the one who gets it when a ninja drips poison down a string while they're sleeping and she rolls under the string at the last moment - I saw this one when I was young and that image really stuck with me all this time. A+ for dying arrangements in this one.
On Her Majesty's Secret Service (1969): This one was actually my favorite for a bit! It held up for three whole days, I think! This Lazenby fellow looks like a cartoon version of Bond, but it's okay, it's mostly his stunt double doing high-velocity bobsled fights anyway. And the nepharious plot seemed to involve curing the world's allergies...
