If you have sex you should watch it.
If you are in romantic love you should watch it.
If you love a victim of sexual violence you should absolutely watch this movie.
If you are interested in tantric sex you should watch it- yes, it goes there. Also if you love 90s Lifetime movies, and Twin Peaks star Sheryl Lee (Laura Palmer herself, playing traumatized sex abuse victim, again, but more nuanced this time.)
I truly love this movie. I came for Sheryl Lee and the promise of steamy psychosexual romance, but was pretty blown away at it's handling of waning desire in a long-term relationship, female "frigidity", male loneliness, therapy, sex therapy, discussion of borderline personality disorder (BPD), and surviving incest.
It starts off feeling 90s, vaguely sexist but relatable guys, high-strung, neurotic wife and tension at home. But it unravels it all so well.
Strongly recommend.
