Have you ever watched "Joan of Arcadia". There are few sexual situations, but I find it in many ways disturbing at a much more fundamental level. "Joan" talks with "god", but the tasks "god" gives her are quite banal. "Joan of Arc" she isn't. Neither is she a female Moses.
Joan is a good show, though declining in quality this season. Sexuality has been touched on in the show, though not a major plotline in every episode it isn't taboo.
My problem with the show this season, is that unlike Season 1, they have gone out of their way to make everyones life and the events in it a huge drama. Not overly suprising as many shows like this tend to degrade into this rapidly by scriptwriters.
I hope it will improve.
