Exactly. Black Widow failed not because it was put on a streaming platform, but because it was a painfully average movie.
Johansson's sexism talk probably hurt the movie more than Disney+. Insulting your own audience just isn't the best way to advertise your new movie.
Godzilla vs. Kong did great despite being released on HBO. Black Widow had a similar debut as other Marvel movies, but failed to grab an international audience and tanked hard after the first week. Here in Europe, people don't care much about that comic character either and demand for superhero movies has been mostly saturated.
Johansson is just salty that her movie bombed and now she's getting greedy while being courageous enough to burn some bridges after her character's death. I think the multi-millionaire can do without you guys rushing to her defense.
