If you’ve been asking why Scarlett Johansson’s Black Widow character can’t get her own standalone Marvel film, consider this maybe a case of be careful what you wish for. “Saturday Night Live” picks up the slack where Marvel has been lacking, offering up a trailer for a film focused on the female Avengers, and well? It’s not exactly “The Winter Soldier,” unfortunately. “From Marvel Studios and the writers of ’27 Dresses’ comes the story of a superhero and her super romance,” the trailer goes. It would be a lot funnier if I couldn’t actually imagine someone at the studio thinking is in fact a good idea. RELATED: What to expect from ‘Age of Ultron’ Follow Ned Ehrbar on Twitter: @nedrick
