I have a love-hate relationship with Moore's Bond films. When I was young and could not judge a film's qualities objectively, I ate Moore's films up like candies. Big explosions and silly one liners. I was happy.
Nowadays, I think Moore only had three truly good movies in his entire tenure - The Spy Who Loved Me, For Your Eyes Only, and Octopussy (my personal favorite of his run.) That being said, only A View to a Kill is truly abysmal (though Walken saves it to some degree). While Live and Let Die, The Man With the Golden Gun and Moonraker have dreadful plots, cheesy special effects, horrible acting, stupid action sequences, etc., they're all insanely entertaining. And heck, Moonraker has one of the creepiest scenes in the entire series when Drax sics the guard drogs on Corrinne Dufour.
Also, I have watched both of Dalton's films recently, and the man deserved to go further with his take. Both of his films easily rank in the Top 10 and The Living Daylights may be in the Top 5. I also think License to Kill would've been a great way to permanently end the series in terms of story arc (though Goldeneye is an even better movie).
