To porn or not to porn?

My partner and I just saw Inside Deep Throat, and it's raised alot of questions. I've had a pretty loose opinion of porn, a sort of live and let live attitude with a little healthy curiousity mixed in. I own a few works of literary porn (novels by Anonymous, small magazines with names like Vibrations and Deviations), the Erotic Universalis by Taschen (17th century woodcuts are HOT!), and the film Behind the Green Door. I watched a little bit of contemporary porn with my ex, but it didn't really turn me on. I'm more into the "artsy" porn.

Anyway, the documentary, in its final minutes, really makes a case for the difference between the filmmaker-driven/revolutionary erotic movies of the 70s and the mass marketed, plotless porn of today. And I have to say there is something to it - you can almost feel the difference (pun intended) between the natural young women in the old pornos and the bleached, sculpted artificiality of today. Even though their attempts were flawed, the people in the 70s had a sort of naivete that makes their product more palatable to me.

So now I'm conflicted, because it seems erotica has lost it's heart, and the liberated have become the subjected.
