Coming on the heels of the conservative Sutherland Institute's complaints that Sundance celebrates "obscene" films, it struck me during the screening of "Don Jon's Addiction" that Joseph Gordon-Levitt has produced a powerful anti-pornography film.

Considering conservative religious groups see so-called porn addiction as a moral plague, they might want to catch a showing of "Don Jon" when it hits theaters later this year. (Full review here.)

Well, maybe not.

The problem, of course, is that they'll have to sit through a lot of low-rez porn as "Don Jon" builds its case before it delivers its witty and, yes, sweet message: Pornography and objectifying women undermines meaningful, not to mention hot, sex.

Gordon-Levitt's point is a bit more nuanced than that. The film hints that "good" porn that includes the woman's point of view is OK.

World-wise Esther (Julianne Moore) convinces studly lothario Jon (Gordon-Levitt)  that sex must be a two-way erotic adventure to create a truly transcendent orgasm.

If nothing else, Esther's good porn = good sex theory cries out for a Sutherland Institute probe.
