You know, I read the Casino Royale book over the holidays. Daniel Craig's Bond is definitely similiar to Book Bond. However, I found it to be a case where I enjoyed the movie better than the book. More exciting and fleshed out the Vesper character more. But considering the movie was adaptated fifty years later, they stayed true to much of the overall story.
That being said, Quatum of Solace still sucked balls. The new kind of Bond film doesn't have to be boring and joyless.
