Come on! EVERY Bond gadget has a contrivance to get it used....
Ah, Mr Bond, you have an exploding briefcase. Let me try open it.
Ah, Mr Bond. You have rocket cigarettes. WOuld you like to smoke.
So, Mr Bond. You car has a passenger ejector seat. Allow me to put my man in it so you can shoot him out of the roof.
No, GE is no different with the pen-trick.
Nooooooooooooo, I disagree.
Any villain might plausibly try to open your briefcase.
Any villain might plausibly try to threaten you while in the passenger seat of a car.
A double click activated pen in the hand of someone else? Who is going to ever DOUBLE click any kind of a pen WITHOUT writing something? They had to design Boris' wholey unnatural pen habit, establishing his quirk in the earlier part of the film, just so it seemed remotely plausible for Bond to get out of the computer room pickle. I bet to some degree they built Boris' entire obessive, techno-nerd character around that pen, trying to justify why in hell he'd ever activate it with it's relatively complicated detonation process. Why not make it one click, even? It's just so awkwardly obscure and moment specific where Bond's fate depends entirely on unbelievable coincidence.
It always seemed extremely artificial that the extremely artificial nerd stereotype Boris was established so early on in GE, clicking his pen away in that grossly unnatural fashion. It actually feels like the filmmakers were trying to prove a bit of net-nerd commentary with that pen trick, rather than use it as a throwaway plot device, which they probably weren't. Again, if anything it just further illustrates how out of touch the Bond team were with their depiction of net/computer culture, aspiring to be a relevant "techno-thriller".
