I watched the movie. I am the target audience for the movie. I want an expanded spiderverse.
The movie was bad. Really bad. Direct to VHS bad. Terrible movie. The actors were OK, but the script was garbage and the plot was nonsensical. Why did the bad guy sound like Schwarzenegger in Hercules in New York? Why did the special effects look so bad? None of the super powers made sense. The costumes looked ridiculous and amateur.
The movie was bad.
There are a lot of misogynists online that took special glee in watching the movie fail. They piled on to make everyone aware of how bad a female-led superhero movie was.
There are a lot of film critics who are tired of comic book movies and enjoy trashing every comic book movie as it comes out. They also piled on in the hopes that they could signal the end of comic book cinema.
So, she's not wrong. This movie never stood a chance against all of the people online who were hoping it would fail, because this movie was a hot, wet, splattery fart.
If we want to talk about the way people trashed The Marvels, that's a different conversation. The Marvels wasn't great, but it wasn't nearly as bad as critics and misogynists wanted it to be. Pro-tip, anyone using the word "woke" in their critique is a dipshit with an agenda. Disregard their opinion whole cloth.
