Pffft, fools not understanding there being two sides to the Bond coin. There is super serious and then there is the absurd, TWINE and Moonraker are both the epitomy of absurdity, especially Moonraker. Sure it was a cash grab, but it was a BOND cash grab. It climaxes with a confrontation with Jaws the man with metal teeth on a space station, Bond convincing him to switch sides, dumping the villain out of an air locker, both Bond and Jaws getting hot chicks to have sweet making fuck with and then Bond shags a chick during reentry. Moonraker is a fucking masterpiece it is the epitome of 1970s holywood cinema, it is nonsensical in the ways that all the best 70s cinema is and chock full of excess in ways that only Holywood can do. It is probably Roger Moore's best film.
If you want a good time you could go with A View To A Kill, that movie pretty much sucks and is a crappy Moore movie then you have CHRISTOPHER WALKEN SCENE and then you go back to sleep, it bounces around between WALKEN WALKEN WALKEN and majour snooze.
If you want to be a big baby and watch serious Bond movies then you will want Casino Royale and I would honestly go with You Only Live Twice. With that you have Connery with 5 other Bond roles under his belt, you get Blofeld who is fucking awesome and to top it all off the screenplay was written by Roald Dahl of all people.
Alternately if you are going for the sexy well then you want Thunderball for incredibly obvious reasons.
Fuck. Yes.
Aaaaaalllllternately, if you are going to be binging on a LOT of Bond, make sure you ignore all the complaints about On Her Majesty's Secret Service and watch it for yourself. For all the issues there is to the movie, George Lazenby was not it and it is really a shame he only had that one honestly pretty shitty script to get to do his work as Bond. A lot of the darker serious Bond stuff you will find later after the much more camp Roger Moore years stems from Lazenby's take on Bond. OHMSS may be a bad Bond movie because it has Bond getting married, on the other hand it also is really freaking brutal and ends with her being gunned down in front of him. If you think the ending of Casino Royale is harsh and brutal it has NOTHING on OHMSS which has credits rolling as Bond clutches his newly wed wife's still warm corpse.
