One of the nifty things about this film is that throughout it, I was wondering about the music. None of it was Bond music, not the guitar, not the trumpets, nada. Until the final scene, when he really WAS the Bond that we all know and love, and bam! In comes the theme song. I left that theater with a mile-wide smile.
As for all the flak that Craig has gotten as Bond, I'll admit that he did a decent job of filling the role. For this film and character, with it's tone and darkness, Craig did awesomely well. But if the next one is supposed to have a "regular" Bond, with all the wisecracks and grins, then I'd be a little more unsure. Pierce Brosnan has always epitomised Bond for me, and it'll take a lot to convince me otherwise.
