*yawn* Oh neat. James retired so they found a new double-o agent to take his spot. Boy that's not uninspired writing. I dislike Neal Purvis and Robert Wade. Casino Royale was their only smash, and the third act had to be completely re-written anyway.
The double-o's are just a code/ a department of MI6. The only other double-o that doesn't routinely get killed in the films is the never seen 008 who M always threatens to replace 007 with on missions.
Let's not forget that this is hardly the first female double-o agent, but just the first that isnt a passing reference to the double-o's where we see a female in a group shot (The World is not Enough, Thunderball).
Also, it's a movie, so who gives a sh*t. I never understood the hoopla over handing 007 over. The story is about James Bond, a named character. Too much emphasis is being placed on his code. It would go on with his name anyway.
I can't wait for the inevitable 007 spin off that Lashana Lynch will star in for Sony/Columbia in 2023. Which will compete against a FOX (Disney) EON Productions remake of the Sean Connery era James Bond films staring Richard Madden as James Bond. Stupid Thunderball/Kevin McClory.
