Im more of a 40's-50s person myself, but I have much love for the 70's.
One Flew Over the Cuckoo's Nest and Godfather I and II are to me the best films of the decade and some of the best acted films of all time. I dont think I have much to say about them that hasnt been said before.
Alien and Jaws are the quintessential horror films. If you were to add 1982's The Thing, those 3 would make the best 3 horror films ever made.
I have a soft side for John Cazale, so Dog Day Afternoon and Deer Hunter are also standouts of the decade to me. I wish more people watched them, cause I feel those 2 films are fantastic and yet not that much talked about anymore. Kinda faded into obscurity a bit.
Other than that, Apocalypse Now, Chinatown, Annie Hall, Patton, Network, Kramer vs Kramer, The French Connection. All of them are rather more popular and all of them are fantastic films. Never was a fan of Woody Allen, Annie Hall and Blue Jasmine are the only films of his I've really liked if memory serves me right.
Superman, Rocky and Star Wars IV are worth a mention as well. Comes off as very cheesy, but Superman used to be one of the best superhero films back in the day.
Weirdley this is the decade Disney Animated films let me down. When I was a kid I disliked The Aristocats and The Rescuers. Felt they were boring. Robin Hood was alright, even with its recycled animations. "Everybody wants to be a cat" is a great song tho lol.
Also, Nashville > Grease.
Sorry for my bad english.
Yeah, most of Woody Allen's movies are lame and stupid. They broadly follow the same type of premise and have gotten more and more disconnected from reality over time as the rule, in my observation. Most of his better pictures were released in the '70s and '80s. But Annie Hall and Manhattan are both just joys to watch. Annie Hall makes me laugh so much!
And yeah, the '70s were not good to Disney. Their, as the kids then would've said, square, family-friendly brand was simply not in tune with the times and they seemed to put relatively little effort into many of their films during this period. The result was that they often came off as generic and fake. Their film adaptation of Escape to Witch Mountain was something of an exception to this rule. The Disney renaissance didn't really arrive until 1989 with The Little Mermaid, though I would trace its origins to what I regard as kind of a breakthrough, if more obscure and less heralded, animated picture in 1987's The Brave Little Toaster. (Of course maybe I'm biased by the fact that The Brave Little Toaster was the first movie my mom took me to see in a theater (), but still, it really was creative and fun I think in a way that Disney cartoons hadn't been in some time before that.) But I know I want to be a cat.
