Well, I can see why you say that, sure. Casino Royale was a straight reboot of the lore to re-define Bond to reflect Daniel Craig's age. But personally I define the reboots as 1969 (1), 1973 (2) 1986 (3) 1995 (4) and 2006 (5). Even if you don't want to call every casting a reboot, then it at least rebooted stylistically with Lazenby, the Moore era, Licence to Kill (which tried to be grittier... and GoldenEye was a reboot, you can't argue that at all.False. The franchise has rebooted itself exactly once, with 2006's Casino Royale.
So I disagree it was just once.
