It's a succession of gags, puns, and visual effects taking place in spectacularly designed settings, spoofs of German expressionism, psychedelic imagery, and all that.
The five disparate directors saw to that, to the extent that the writers didn't. It's pointless to compare 'Casino Royale' to any of the other 'straight' Bond films. Or in Fritz Perl's 'here and now', to switch hoaxes in midstream. It helps if you're able to live in Kierkegaard's unfolding moment if you want to enjoy this movie.
