You Only Live Twice

This one is a triumph for Ken Adam's sets. The volcano base is the most memorable feature of the film. Oh, the story is fun and the gadgets are cool, but those sets really sell the film. They would inspire countless imitations and variations throughout the years.

Finally, we get to see Bloefeld, and it's a bit of a letdown. Donald Pleasance is a fine actor, but he's not quite supervillain material; more of the serial killer variety, in the mold of Peter Lorre. Still, he is by far the superior on-screen version.

The Japanese cast are all outstanding. Special mention should be made of Peter Maivia, grandfather of Dwayne Johson, aka The Rock. He and the stuntmen create a brutal fight scene, second only to the train fight in FRWL, although this is perhaps more inventive.

As for gadgets, outside of the jetpack from Thundrball and Goldfinger's Aston Martin, Little Nellie is the coolest ride. The aerial scenes are spectacular and are one of the highpoints of the whole series.

This film really marks the end of the ultra-cool Bond films. After this, they tend to go down in quality, taken as a whole. Some have better stories and villains, some have better stunts, but they are never the complete package that the earlier films were. Still, this one (along with Goldfinger and Thunderball) would inspire every spy work that would follow; from The Man from U.N.C.L.E. to Our Man Flint, Marvel Comics' Nick Fury, Agent of S.H.I.e.L.D., to the X-Men. Everyone stole an idea from here.
