Take the motorcycle chase - with the exception of the Brody statue (which I would have hated even if it wasn't CG, which I'm not entirely sure it was), the rest of the chase wasn't CG at all.
What about the graveyard sequence? That felt pretty real. I'm fairly certain that wasn't green-screened.
Did they use too much CG? Hell yeah. But saying "most of the movie was shot on green screen and phony cgi instead of on location" is just plain false.
