I consider myself a feminist, and I don’t get most of the criticism being thrown at Age of Ultron and Joss Whedon.
Even if you didn’t like the Natasha/Banner relationship, Black Widow still had a ton of badass moments in the film. Their relationship didn’t distract from her badassness. Also, why is no one talking about SCARLET WITCH?! Wanda was an integral part of the film, and she was fucking phenomenal. Helen Cho was an interesting, three-dimensional character as well despite her relatively short screen time. Peggy Carter, Maria Hill, and Laura Barton didn’t leave as much of an impression this time, but Peggy’s off being a BAMF in Agent Carter.
Does the Marvel Cinematic Universe have representation issues? Hell yes. But don’t try to shove all that on Joss Whedon (one of the most outspoken feminists in Hollywood).
