Tough to decide between the 70s and 80s for me. I'm going with the 70s based on some of my favorites like Jaws, Close Encounters, Taxi Driver, The Godfather, Apocalypse Now, Dawn of the Dead, Halloween, Texas Chainsaw Massacre, American Grafitti, Blazing Saddles, Chinatown, The Deer Hunter, Deliverance, Dog Day Afternoon, M*A*S*H, Rocky, Mean Streets, Serpico, Superman...on and on...
The 80s aren't far behind with movies I love like Ghostbusters and Ghostbusters 2 (greatest movies ever made!), Gremlins, An American Werewolf in London, Day of the Dead, Evil Dead 2, Re-Animator, Bad Taste, Poltergeist, Return of the Living Dead, The Thing, Do the Right Thing, Raising Arizona, Indiana Jones Trilogy, Raging Bull, The Elephant Man, Platoon, Purple Rain (
), Scarface, and on and on again...
Man I love movies. Now that I think of it, the 40s, 50s, 60s, and 90s have probably just as many favorites...but I'm still partial to the 70s and 80s. The 00s have flat out SUCKED for movies. Hollywood has gone to ****. I don't even bother renting new movies/going to the theater anymore.
