I believe with all the cloak and dagger type movies coming out in the last 10 years, and being able to draw an audience, the Bond movies don't need to go to the extreme with the gadgets like they used to. It's almost like how campy the Batman movies got, then Nolan did a more gritty real world take on the series. I think Bond is going in the same direction, less camp with the gadgets, villains, secret hide outs, ect.. more real world take.
I liked Casino Royal. Bond didn't have missle launchers, lasers, amphibious stealth cars, to get the mission done. However, he did get a set of bionic gonads after the whole knotted rope incident. Quantum of Solace wasn't all bad, but the whole exploding hydrogen fueled hotel at the end seemed a bit piontless.
I think Skyfall seems pretty good so far.....at least the 1min 38 sec I've seen so far
