In next April's Captain America: The Winter Soldier, Scarlett Johansson's Black Widow will once again play second fiddle to a male superhero, just as she did in Iron Man 2 and Avengers Assemble, though her contributions in those films suggest she would be just as capable of going it alone as Thor or Hulk or the rest of the gang. DC now seems to be following Marvel's example by shoehorning Wonder Woman into its Batman vs Superman testosterone tussle, even though she was the central character in a well-known 1970s TV show, and her comics have been published almost continuously since 1941. What more does a superheroine have to do to get her own movie?
