My favorite decade of horror films was the 80's, probably because that is when I got into horror, both written and on film. I rarely read horror these days, but I still enjoy horror movies, mostly older ones that I own or check out from the library. Every October for about the last 15 years my wife and I go through our favorite horror films in the evenings - The Shining, Halloween and Halloween 3 - Season of the Witch, Rosemary's Baby, Bram Stoker's Dracula, The Thing, 'Salem's Lot, The Silence of the Lambs. We also enjoy a couple that are horror with a wink to comedy and campiness - Thinner and The Phantom of the Paradise. Then there are some intense ones that I enjoy but my wife won't watch - The Texas Chain Saw Massacre, The Funhouse and It.
In Shock Value: How a Few Eccentric Outsiders Gave Us Nightmares, Conquered Hollywood, and Invented Modern Horror Jason Zinoman discusses the decade of the 70's in horror, with a few examples just before and after that decade. The most important phrase in his title is "conquered Hollywood". Major film studios did not put much money or effort into horror after the very popular Universal horror films of the 30's and 40's: Dracula, Frankenstein, The Mummy, The Black Cat and The Wolfman. But when the public flocked to the films that Zinoman discusses in the 70's, Hollywood definitely took notice and got in on the action. Obviously the upside of that development was that we started receiving a steady stream of horror. One of the downsides was that independent filmmakers were largely outflanked, so that horror films tended to be more formulaic.
Zinoman uses 9 films of that era to make his point. Each film is reviewed in terms of its strengths, and is used to discuss one particular issue in the horror film "industry". Zinoman uses quotes from their directors, producers and actors. The films and their directors are:
Halloween, John Carpenter
Carrie, Brian De Palma
The Night of the Living Dead, George Romero
The Texas Chain Saw Massacre, Tobe Hooper
Dark Star, Dan O'Bannon
The Exorcist, William Friedkin
Last House on the Left, Wes Craven
Rosemary's Baby, Roman Polanski
Alien, Ridley Scott
There was a comment by director Wes Craven that I enjoyed:
"The first monster that the audience has to be scared of is the filmmaker. They have to feel in the presence of someone not confined by the normal rules of propriety and decency." I don't think that someone who doesn't agree with that statement can truly enjoy horror. On that subject, although Zinoman did broach the topics, I would have been interested to have seen a much larger discussion on misogyny, gore and gratuitous nudity in horror. I'm sure the latter has primarily to do with revenues, but all can still be important subjects for discussions of artistic and social merit / harm / artistic freedom / censorship, etc., etc.
Other interesting comments had to do with what changed when "New Horror" arrived:
Director John Landis: "The majority of (early) horror and sci-fi films were not badly written, badly acted, or badly made - until the monster shows up. And then it's some guy in a stupid monster suit. The monsters are stupid and the plot is smart. That changed in the seventies when the plots became stupid and the monsters smart."
Author Jason Zinoman: "The New Horror was darker than earlier movies. The gloomy ending became common. ... The central message of the New Horror is that there is no message. The world does not make sense. Evil exists, and there is nothing you can do about it."
