The 1970's truly sucked.
Not in the film sense, mind you. It was a great decade for films, and one of the best thing about the films from this decade is that they remind you just how much the era sucked!
There is a tendency for all of us to romanticize the times when we were kids. I had recently found myself falling into that trap by watching certain TV shows from the 70's--stuff like The Bob Newhart Show. But in the last few months I have been catching 70's movies like "The New Centurions." "Dirty Harry" has to be the ultimate film to remind you just how bad that decade was. I was 6 in 1970, and as I grew through the following years, I had a sense of a world increasingly spinning out of control. In particular, the people around me walked around with a attitude of resigned victimhood. There were a lot of components to this emotion, but certainly crime had a lot to do with it.
"Dirty Harry" highlights all of this so well. When Chico and Harry are driving through the seedy section of San Francisco with all the strip joints, a lot of people in the audience must have nodded their heads when Clint observes that he'd like to throw a net over all of them. By 1971, the general public was also getting a sense that court cases such as Miranda had turned the justice system against them. If you lived in the 1970's, and you prod your memory a little bit, you'll be able to come up with another thousand examples of what made the period so bad.
In the end, perhaps the best thing about motion pictures (and television, for that matter) is that it will paint a vivid picture of times and places for future generations. People will have to wade through "The Brady Bunch" as well as "Dirty Harry" in order to understand the times, but overall, I think film has done a pretty good job of reflecting times, and in particular, how those of us who lived during a particular time looked at the world around us. When I talk to my peers, there is a consensus that America hit rock bottom in the 1970's. I think "Dirty Harry" has done a great job of conveying this.
