The 70's
I hear this over and over and over again, mostly by loser fanboys that see in DeNiro, Fincher, Nolan, the man of their dreams and who, predictably, haven't seen anything done prior to 1970. Charlatans like that worm looking director that recently got accused of sexual assault also promote this lie. Now the 70's is the decade that established the modern style of filmmaking, it did away with the classical style, and all films since are in the language of the 70's, but that's not saying much given the execrable quality of modern day filmmaking.
What the 70's gave us was basically ugly grainy photography, explicit violence, jump cuts and annoying closeups of irrelevant actions as a way to give an "artsy" mood, that's it. At the end of the day, this is NOT the best style to effectively tell a story or to create art, the classical style, from silent films to late 1960's, is. They got it right. How do I know? Because when you spend a year looking at those old films like I have, the post 70's films become unwatchable, since the style is so jarring, you are reminded there's a camera with EVERY SINGLE SHOT. It's awful.
So educate yourselves and stop lusting for Fincher or Nolan's cock.
