I share the OP's opinion on the films in question (The Godfather & Scarface), it must be said, though I saw both of them before I knew anything about cinematography, so I may have missed something interesting there. However, I have absolutely no interest in a second viewing to explore this theory.
I also hated almost every single character.
It should be noted that I'm quite a fan of the cerebral film experience, and have watched any number of critically acclaimed films from the French and Czech New Waves to much more modern stuff, but these in particular fell utterly flat.
