This picture is full of beautiful, healthy, prosperous people with active sex lives, and yet they're all miserable!
Shower and Agee's characters are tired of each other. Despite their attraction, they're not enjoying their lives together. They have sex out of a sense of marital obligation.
Carolyne Smith's character is young and cute and ready for love, and instead of enjoying herself becomes an exploitive, manipulating little fiend.
The daughter is there only to give Shower's character a hard time. What a waste!
This picture is a puritanical lecture about how no good can come of healthy sexuality, and the best you can expect of life is a faithful spouse, and if you're good and faithful you won't get involved with bad people who will wreck your life. Yecch.
Kathy Shower and Lisa Comshaw are beautiful to look at, especially considering their ages. Their lesbian "relationship" brings nothing but pain and anxiety. There's no love in it, just domination and exploitation. It's a nasty, homophobic theme, and must have been written by someone who doesn't know any real-life lesbians.
Carolyne Smith is gorgeous to look at, and sexy as hell in this role, despite its misogyny. But her character is sick and hateful, and self-destructive in the end. I enjoyed her a lot more in the comedy _The Naked Detective_, because *that* character was enjoying life. People who are enjoying life are more attractive than miserable people.
The title on the box in the video store is _Boundaries_, not _Erotic Boundaries_.
