I actually quite enjoy the Moore Bond films, even though they are often too silly for their own good. There are a lot of really good spy movies buried under the jokes and slapstick, though, and I feel like you could remove about 10% from each Moore film (JW Pepper, Bibi Dahl, etc.) and you'd have almost perfect movies.
Live and Let Die. Half blaxploitation, half Smokey and the Bandit. A weaker entry but still fun, and I have a soft spot for it since I grew up watching it over and over (and over and over). The voodoo aspect is interesting, there are some great (if unnecessary) car stunts, Jane Seymour is an interesting and beautiful Bond girl, and Moore gives a solid debut that quickly makes him stand apart from Sean Connery. If we could just get rid of some of the unfortunate racism, JW Pepper, and Yaphet Kotto's exploding head, we'd be on our way to a much better film.
The Man with the Golden Gun. A solid espionage movie buried under bad jokes and an obsession with bums. The spy plot is solid and Christopher Lee is great, plus it has my all-time favorite Bond stunt (the car jump). Alas, we also have karate schoolgirls, sumo wrestlers with wedgies, and a godawful fight with NickNack (whose inclusion in the film is never embarassing until the end). Oh, the movie this almost is...still decent, though, for what it does have.
The Spy Who Loved Me. Everything the two prior Moore films wanted to be but didn't quite manage. It's big, over the top, silly in the right ways, with a gorgeous and capable Bond girl, stunning locales, amazing action, a menacing henchman, and a wonderful title song and sequence. The villain is a tad dull and his scheme is just You Only Live Twice underwater, but other than that it's a great flick!
Moonraker. Really an embarassment for all involved, although it's still fun in a very non-Bond sort of way and has some good moments. It's so ridiculously absurd and over the top (in a bad way), though, that it can't recover. And that chase past all the billboards is the most blatant case of product placement ever. And Jaws turning good and falling in love? Are you kidding? Ughh. I still love that pigeon-shooting scene, though.
For Your Eyes Only. A terrific espionage film, by far my favorite of the Moores and one of the best in the whole series, IMO. We have a great plot that never gets bogged down by action (even though there's a TON of it), a multi-layered Bond girl, a solid villain, stunningly gorgeous locales, great stunts, and a greater script. If not for the inclusion of Bibi Dahl, this would be in my top 3 Bond films of all time. As it stands, it's at number 5.
Octopussy. Another solid entry that gets a bit more bogged down in silliness than it needs to (the Tarzan yell, for instance). The plot is terrific, though, with some good old fashioned espionage involving betrayals and twists. Good villain, great stunts, very interesting Bond girl, and a great henchmen (the one with the sawblade, that is). The India locations aren't nearly all they could have been and some of the film is too jokey and slapsticky for its own good, but still a solid effort.
A View to a Kill. Wow, this film gets such a bad rap! I realize it has flaws, but I also feel its pros outweigh its cons. A good plot (yes, yes, I know it's just Goldfinger again, but who cares? No one seems to care that TSWLM is just YOLT rehashed), some great stunts, a perfect John Barry score, a menacing villain, and some interesting subplots (the genetics testing, the KGB rivalry). Unfortunately, it has a weak screamer of a Bond girl and a very strange villainous henchman (Mayday), and Bond's sex scene with the latter is the most embarassing moment of the series. And Roger Moore was FAR too old to be playing James Bond, and he looks it the whole way. Still, though, the PTS is great, the title song is the best of the series, and the climax is fun. I'm just going to come out and say it: I like A View to a Kill! Now I'll run and hide before I get beaten up....
