Well instead of the gun barrell we got a pretty cool intro. The very first shot with the music put a smile on my face.
I took it that they wanted us to forget about Quantum of Solace. Casino Royale and Skyfall can be taken as one character arc to his development into the full James Bond character. Dirty gunbarrel and less Bond feel in CR, and clean gunbarrel and a solid dose of Bond in SF.
It's kinda ironic how they wanted to get away from it all with the Craig films, and now we're even back with the Connery/Moore era M office.
