First of all we see the agency's improbably youthful and pretty sharpshooter being sternly ordered to take a shot at the bad guy that she simply doesn't have. I don't have a shot, she says, but all M barks in return is Take it anyway. So she does and, surprise, surprise, hits Bond who then falls hundreds of feet and sinks into the depths of a rushing river, only to reappear some time later virtually unscathed physically but a bit the worse for wear psychologically (and who can blame him?)
Then he's allowed back into active service, despite failing on most of the criteria by which any agent would normally be allowed to do so.
Later on, we see Bardem's arch villain character incarcerated in a cage that would have Harry Houdini scratching his head about how to get out of but then, miraculously and with no explanation at all.....he's out and about causing mayhem again, not least on the underground rail system which, apparently all by himself, he's managed to rig to send a speeding train plunging into a void carryng lots of innocent passengers.
And then, towards the end of the film, instead of being taken into the protective custody of a crack team of MI5 (or is it MI6?) agents, for no logical reason, M scoots off to the wilds of the Scottish Highlands and gets herself killed to make way for Ralph Fiennes to move up the career ladder.
The music's good (I have the soundtrack) and, thanks to Sam Mendes' direction, the general 'look' of the film is pretty good, but overall I left the cinema feeling that more than any other Bond movie, it was all style and no remotely credible substance. Very disappointing.
