When she says, "I don't need a 40 year old white dude telling what didn't work in 'A Wrinkle In Time'", that's not good (notwithstanding the fact that that movie sucked because it strayed from its source material so terribly that no one wanted to see it.) Besides, does she not realize that there are hundreds, thousands of YouTubers out there producing content? If she climbed out of her Hollywood bubble and hit up the googles, she'd see that there are many, many women out there commenting on movies. Just because they're not working at Marie Claire, Cosmo, Entertainment Tonight or Entertainment Weekly doesn't mean they're not out there.
Besides, entertainment is supposed to be for EVERYONE; a white guy can listen to NWA, American Indians can watch Bollywood films, Satanists can watch "Left Behind", etc. Anyone can watch a Marvel movie and be entertained.
It's a bad move to say what racial, sexual or ethnic group is supposed to consume. That is very sexist and racist.
