While it wasn't brilliant, there were aspects of real swinging that were fairly well covered. If anything, it's a good movie to watch if you're in a swinging couple or open relationship as the pitfalls are well categorised.
It doesn't really matter if it's real or recreated or scripted, as the issues covered are real. Speaking as a swinger myself, it does show the difference between social/emotional and sexual relationships. The older couple has a better view, that you have to be very strong in your relationship and have very firm ground rules, such as not 'playing' separately, or keeping the other informed of whereabouts.
Emotional attachments are a lot harder to deal with than casual sexual liaisons (ask anyone accused of having an internet "affair" when they've never met - its emotional infidelity) if both partners agree. But both do need to agree, and pressure is a no-no. All of this is shown in graphic detail in the movie.
Not so good if you're just curious about the lifestyle, more geared towards those already in it, or just starting in it. Best of luck!
