Zao's "gene therapy" procedure is interrupted, leaving him hairless, with pale skin and icy blue eyes — yet his face is still diamond encrusted from his first encounter with Bond. If he was hoping to change his identity, wouldn't that have been the first thing the doctor would've removed?
Vanity is one of the Seven Deadly Sins.
Bond uses the ejector seat to revert the flipped car... and minutes later puts Jinx in the seat that shouldn't be there!
No, he doesn't—he kind of lays her down in the space where a seat should be.
The concept of the bad guy as a North Korean leader with dreams of conquest who was able to turn himself into a Westerner who is being worshiped by the Western World and who has a hot blond babe in love him may be cheesy, but we did have a certain North Korean leader who had been known for having particular... obsessions with the West. Whether the knowledge of this parody makes the movie all the more enjoyable or not is up to the viewer.
Ironically, Kim Jong-il was a huge fan of this series until this movie came out.
The Vanquish conceals itself thanks to tiny cameras all around it. Fact. But what happens when snow falls on the roof? Somebody might go, "Gee, that snow isn't quite touching the ground. In fact, it's falling in the perfect three-dimensional representation of a car. Oughtn't I go check this out?" Worse yet, the cloaking effect would be ruined when it's hailing taxis outside.
Hell, even the slightest paint scratch or dent in a body panel (from collision damage or bullet impact, both of which happen to the car a lot' during the XKR duel) would throw off the camouflage by distorting the image or damaging the equipment needed to maintain the image. How also does it avoid projecting the car's shadow on the roof?
Objects passing behind the car appear to be closer than they are, such as John Cleese's legs in the briefing scene. How is this not a dead giveaway?
Even with the visual stealth, we know for a fact that the car isn't silent. That's a V12 engine in there, it's going to be loud, even idling. We even see one of the guards perk up for a moment when he hears the sound of a car engine, but he dismisses it.
A scene in which Bond hides behind his Vanquish, with its cloaking device. We've been given an explanation of how the Vanquish works, which means Bond's image should simply be reproduced on the other side, visible to the guard.
It doesn't seem as if he's really "hidden," just in cover in case he's spotted and someone starts shooting. He may just be crouching out of habit, or because a crouching target is harder to spot than a standing man.
Miranda's supposed fencing skill winds up being an Informed Ability when she flails around to little effect against Jinx. Except she's not using fencing weapons, and she's facing someone who (ostensibly) has been trained in knife-fighting. Also, Olympic fencing is strictly limited in terms of rules anyway. If anything, it's impressive that she managed to land a hit on Jinx at all.
When Graves flaunts over his ability to use Miranda's sexuality against Bond, he merely responds that it's "the coldest weapon of all". It makes sense when you realize that James was likely referring to the events of The World Is Not Enough, when Elektra King seduced him, only for her to be revealed as the Big Bad.
Zao is quite reckless during the second half of the movie, continuing to engage Bond in the ice palace when he could have easily broken off. But his gene therapy was interrupted, and the doctor tells Jinx the first step is killing off all the subject's bone marrow - Zao's living on borrowed time and wants to kill Bond for himself while he can.
Jinx claims to be working for the NSA, an agency that does not send agents in the field. Of course, she is lying to cover her real employees.
Graves/Moon being able to set up a mining corporation within 14 months and even building a working Kill Sat in that time seems like something that was missed, but Moon mentioned that he "had plans" for the diamonds Bond delivered in the Cold Open, it's possible "Gustav Graves" and his corporation was in operation as a shell company Moon had been running before the events of the movie, with his "death" and subsequent gene therapy allowing him to use the cover "for real".
M by the time she sends Frost and Bond to Iceland, already started to suspect Frost, watch her conversation with Frost again, knowing Frost is the mole, M makes slight allusions to Frost not acting like a standard MI6 agent, she isolates herself, making no personal connections at all with the people she works with, M also outright points out that despite M pretty much already knowing Graves is up to something, Frost has not even found so much as a dust bunny of dirt on him (a subtle callback to the Tomorrow Never DiesGupta's law of Convenient Anomalies) and the fact that she dismisses Frosts protest of having Bond being at Iceland. By the time M had more evidence, she probably figured Bond would be able to deal with it.
It's mentioned that Bond was captured and tortured in Korea for "over a year". This is already a haunting thought, but consider this film released in November 2002. Now what terrorist plot occurred a little over a year before the film's release, one that the governments of the world were helpless to stop...
