The Man With the Golden Gun. Its entirety is summed up in the first 30 seconds past the standard gun barrel sequence; Christopher Lee emerges from a swim and while drying off, the camera zooms up on his hairy chest to make emphasis of the character's third nipple. It's the weirdest of the bunch in a "why am I watching this" sense. There's plenty of camp in most films, but this one is just plain dumb. Especially when Bond is captured and the henchman in charge elects to put him in a karate dojo to fight to death, which he easily escapes.
Also the entire final act and proper showdown is only there because the lead girl got captured. This would be nothing new for the series except it was from her attempting to plant a tracking device at no one's order and after they had already swindled the plot device back. They could have just let Lee walk away and deal with him later.
Moonraker is also often pretty poorly regarded, but I rather enjoyed it up until it actually got into space and went full on sci-fi with laser guns out of nowhere. It was a Star Wars cash-in that recycled the premise of the Bond film immediately before it. The choice of Venice and Brasil for the locales in the first half helped save it for me, I think.
Other hated ones were alright, or I liked enough for their unintended comedic value. Especially the Pierce Bosnan films.
