I sure do, I remember my first adult movie Kadillac and DeVell. Since it was my first I thought it was awesome, the first scene was with Nikki Sinn and I declared her the most beautiful woman in the world. Good times! Sadly I can't find a copy to buy or download so I can have the movie that started it all.
I think today they are more concerned with positioning and staging than letting the natural act and body reactions to take place. There is a scene in "My First Sex Teacher #20" where Darla Crane (who I just think is hot) is on her back on the desk and the guy keeps moving her leg in just an unnatural position so they can get the shot. Her leg would fall back into a more natural position and he would move it again. Talk about ruining the scene. To me let the action take place, and the camera man should be the one that adjusts to what is going on.
