Yeah, the point of James Bond isn't to be realistic, like pixie said. It's more of an outlet and a way to have fun and watch a good action series. I'm not saying the new ones are the best, but they're still James Bond movies. :/
I must say that Quantum Of Solace is one of the worst movies I'v ever seen. And by far the lowliest of the James Bond saga. It was like watching Ironman meets The Matrix[crap on a screen].
