Finally saw this lastnight on blu-ray.
Sam Mendes was a good choice of director but I kinda still felt that Bond movies seem to be outdated these days...
The stunts/action scenes were ok...until you notice the deliberate flat-track on the roof for the bikes to race across OR the grilled platform welded to the bull-dozer's swing arm for Bond to run across.
And it seems harder each movie to come up with a villain that doesn't have a cliched reason to be the antagonist. He had the potential to cause havoc on a worldwide level (like every Bond villain) but then his reason became obscured & convoluted with his vendetta on M. In the end, the bad guy did a half arsed job with all the computer tech he had at his fingers.
