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 never been a fan of the Slasher genre, I personally find it a bit boring and not that scary, so I was never big on Halloween, but it been such an influential film I guess its worth a mention.
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.
