Plot development, as always, was very good. Action-scenes were quite new, as Bond has never been known to be a parkour (free-running) practitioner. I think the script-writers took a little liberty with Craig, making his Bond a little grittier. Not too bad, I suppose, but I'm sure Bond fans would probably take some time to get used to it. I know I will. I did not like the Bond girl for this movie. Didn't really complement Craig very well, and they were needlessly romantic. Bond is a slick player, not a heart-melter. Still, it was a James Bond movie. :)
Looking forward to Quantum of Solace.
