FYEO and TSWLM both return to the classic formula while not feeling like "retread", especially FYEO. Indeed, FYEO would have come immediately after TSWLM had it not been for Star Wars, which prompted everyone to go into space - including Bond but Moonraker has a number of fantastic set-pieces despite the outer space stuff, which in retrospect may have helped FYEO be given that much more epic a script. These two show Moore's era at its finest. And FYEO, after Moonraker and Moore's first two outings - feels as much an apology as it does a mini-reboot. The music might be off in some scenes (it's almost too trendy in spots, but the production team was also looking for a new style instead of the risk of becoming stagnant), but works utterly great in others but the story's flow is incredibly good, and Bond's interest in the Countess, her murder (which harks back to OHMSS as much as the pre-credits bit does but only far better), and his revenge on Locque, is some of the cinema's gripping and all-time best. To say nothing of the plot, the excellent chase and suspense scenes (such as when the baddies follow Bond into the ski lift, it's handled with perfection and Moore's subtle nuances and facial expressions really nail the sense of threat and the audience is tuned in that much more), and the fate for the ATAC device that became the quest for both sides. Nobody does it better-- that is the truth. FYEO is easily Moore's finest, and one of Bond's all-time bests.
TSWLM is Moore's first rock solid great, after a great era opener (LALD) and a turkey that tries to be well-meaning (TMWTGG). Back to basics, Jaws gets a great introduction and use - not overused, not comedic, but downright terrifying. The music is sometimes trendy, sometimes classic, but even the trendy disco stuff doesn't feel as dated as it otherwise might do.
Live & Let Die may be "Blaxploitation" but the acting from all involved just makes the movie feel like a Bond movie that is a bit more realistic, plausible, and - indeed - truly epic than the outings from the 1960s. Roger's first, he does bring in a freshness to Bond, into a story that feels refreshing and exciting all around. Yaphet Kotto, Julius Harris, David Hedison, Lon Satton, Geoffrey Holder, and Jane Seymour all make this movie genuinely riveting from start to finish, with Harris and Kotto vying to steal the show at every turn - there's nary a scene I don't like when either of them in it, they are a joy to watch with their styles. Made in an era of "Blaxploitation", it still comes across as a solid Bond movie first and foremost. FYEO and TSWKM are a bit more well-rounded but LALD is also well above average,
Octopussy too goes back to the basics, even Bond going in disguise. But going in as a clown almost upsets the movie. John Glen, whose directing style rightly dominates the Bond franchise, never put out a clunker. I like it a lot but it's not as much of a thrill as LALD, TSWLM, and FYEO are.
AVTAK feels like a reboot of "Goldfinger" but played straight. Moore still works as Bond despite his age, though it was obvious at the time he wouldn't be returning. Christopher Walken is underused, but given the fantastic performance of Grace Jones as May Day it's understandable. The only problems as such involve setting up the premise with the microchip that promptly gets ignored... and, of course, the use of Beach Boys music.
Moonraker is a bit of an oddball. The movie starts out pretty solid. Moore gets a great bit where he's skeet shooting and kills a would-be assassin then quips a joke. The G-force scene was a great trap. Only when the focus of the movie shifts into outerspace, taking TSWLM and applying it to orbit instead of under water, do things become silly. Wile E. Jaws making a second appearance also drags down the story, but along with everything else in the story it's also kinda nice that Jaws survives and gets a girl as well. But the more outlandish films, regardless if it's Moore or Brosnan or Connery, none of them has held up over time.
The Man with the Golden Gun tries way too much to outdo LALD's comedic style, and flops. Especially with Christopher Lee, expectations were high for a thriller. What we got ended up as being the reason the franchise came back down to Earth with TSWLM. Even Lee is poorly used. This one, IMHO, is the worst of the bunch.
