real/gritty is in. they were trying to make bond more realistic and gritty
I'd argue that the grittiness fad (or whatever you want to call it) began with the Bourne series, but I see what you're saying. As far as straight-up comparisons go, old Bond is to new Bond as old Batman is to new Batman. However, I think you might be confusing the better artistic comparison with what the studio wanted to express in a modern spy film. I think they looked at the success of the Bourne series and wanted to duplicate it with similar elements.
But again, I agree. "Reboots" that are darker and "grittier" did seem to begin with Batman Begins, and they won't end any time soon. The new Lone Ranger looks like he might smoke meth and cut guys dicks off. Should be good.
