That's really ridiculous. Someone call the feminists and get them off of the lego company's case and onto a real case of discrimination. If I had to stay at school while all the boys went on a field trip I'd be really upset.
The fact that the movie is a bunch of left wing propaganda is beside the point, it's more fun to see a movie in a theater than to sit in a classroom and maybe have the option of watching a years-old movie on a small tv screen.
