Poor character development in the movie. I believe more emphasis should have been put towards Black Widow's background as the audience should know what's her story. The movie only gives you simple flashbacks which just don't make it interesting. I also hate the fact that the writers tried to make the film more comical using her family, yet avengers films are meant to be thrilling and action-packed. Lastly, I HATE the fake Russian accents. If you want Russian characters, THEN HIRE RUSSIANS!!!!!
