This is some of the best of old time porn - Anthony Spinelli was cutting edge then and got the women to go over the top. Just for a change of pace, go classic, your woman will like it too, and isn't that what you want.
Back when porn was about acting. The actors in these scenes are acting, that is, there is a plot, kinda, at least, a storyline. Something you can watch an laugh with your honey.
I like the oldies more than most. But, give me a break. It was too much of an attempt at a movie with the stars as dancers. And, not enough sex scenes. Another pass.
