I have to agree with Paul's estimation that Casino Royale is one of the best Bond films in the last 30 years.
Craig is a fantastic Bond incarnation and the first twenty minutes are a blur of physical stuntwork that was both beautiful to watch and excrutiating to imagine doing. What's interesting about this film is pretty much what you've heard: that it shows a more vulnerable Bond; a more adolescent, more impulsive Bond.
And yes, Bond in a wet white tuxedo short. Thank you for that. Please also note his use of the square cut Speedo, which some of you may remember I helped popularize this Halloween.
I thought the film was fantastic—any film that can make a game of poker suspenseful is doing something right. I also thought Eva Green as Vesper Lynd was great, although it was annoying to me that Le Chiffre had an eye thing awfully similar to Blofeld's eye thing.
Which makes me wonder something...
You'll just have to see the film to figure that out.
