As far as similarities to Nolan's Batfilms go, in particular THE DARK KNIGHT...they were pretty basic and minimal, really limited to one key section of the film, and I think Mendes came out ahead there comparitively. SKYFALL is just a more consistent film than THE DARK KNIGHT RISES or THE DARK KNIGHT (though TDK has enough high points that I wouldn't want to begin deciding which is the better film between SKYFALL and TDK).
Yeah, ********. It's more than just basic and minimal. Skyfall, as much as I really, really like it (third favorite film of the year)
, is damn near a remake of the Dark Knight. Right down to the story points and the theatricality of the villain....
