BUFFALO, N.Y. (AP) — It hasn’t even opened but already “Fifty Shades of Grey” is getting a big thumbs-down from religious and other groups who say it’s degrading to women and endorses sexual violence.

One social media campaign is encouraging movie-goers to instead give their ticket and popcorn money to women’s shelters.

Even as screenings sell out in advance, critics, including the American Family Association and National Center on Sexual Exploitation, are pushing for boycotts.

One group in Madison, Wisconsin, is planning to picket outside a Thursday premier.

Author E L James, who wrote the erotic trilogy that launched the film, has heard the backlash and says the critics have it all wrong. She says no woman wants to read about abuse, and that everything that happens is safe and consensual.
