Some shots of The Bat aren't entirely convincing either, IMO.
Warning: Spoiler! (Click to show)Most notably, when it's banking through the buildings, trying to avoid missiles.
Having said that, it's possible that it sticks out to me more, because of the alleged 'reality' its meant to be be inhabiting, as opposed to say The Avengers, which has obvious CG falling out of its ass, but I don't really care, as it's pure unadulterated fantasy.
