"Not true. A sequel would entail a continuation of the plotline. The Bond movies are all considered sequels to the last, yet the lead actor, writer, and director often change."
Also, the plot never picks up where the last left off. Bond girls are always in only one film and they never make mention to old Bond villains. It's kinda of like the deal with FFX-2: each new Final Fantasy game is an entirely new story with new characters and does not carry on from the last game. However, Final Fantasy X-2 is an actual sequel to Final Fantasy X, picking up where the it left off and involving the same character and world. I'm guessing that's what they mean by a "true" sequel to Goldeneye, a continuation of the Goldeneye plot rather than a whole new Bond mission.
Hehe- I just realise, if you sound out the letters of OPM, it sounds like opium.
