It's usually a bunch of incels feeling like they're being attacked or rejected anytime a female-lead film (or most usually, an ad, article, or interview rather than the film itself) implies "girls rule, boys drool."
I hope this movie does well, but more than that I hope it's a good movie. The ads don't instill me with confidence since the BoP are downplayed and I have no idea what the actual story might be. And unless they're keeping it a surprise, not thrilled about superhero characters not being superheroes or having costumes - HQ looks like she's going to an EDM festival more than a comic book character and the others are essentially wearing street clothes (though Huntress seems to wear a mask at some point)
Honestly, the film also has some stiff competition with the "HQ" animated series on DCU. That show has been awesome - it's funny, embraces the full DCU and has some poignant things to say about a damaged character who was in a relationship with a madman.
