95% sex, 5% other scenes
Not kidding! I had been trying to see it for years just out of curiosity and then Jan Michael Vincent passed away and it became a little easier. He is only in it for a bunch of talking scenes unfortunately, the rest is basically the gardener and the housewife making love or daydreaming about sex.
Also, it reminded me a lot of The Room a more recent notoriously very bad film.
As much as I love JMV, I give it a 1/10.
