we don't need another Hulk movie. Bruce Banner can't carry a movie. No one is getting a solo movie from this point forward, they're always gonna inject another character into it, so this Hulk and Thor pairup is brilliant.
same reason we don't need a fukkin Widow movie... and if they insist, they might as well make it a Widow/Hawkeye movie, and add one of the major characters in for half the movie. she was basically the co-lead in Winter Soldier anyway. Count up her screen time in the MCU and it easily adds up to a movie.
Unfortunately they HAVE to make a Widow movie to appease the feminists.
