Yes, I absolutely do believe it's worth taking a critical gaze at romance novels and films, where "critical" means "assessing and evaluating" and not "find everything wrong with it". And yes, I'm okay with men doing this too.
But also, I somehow think that if I, as a woman, launched a Youtube channel where I read military novels and watched action movies and invited military women to laugh with me at all their silly or improbable or problematic bits, I would not get nearly the same reaction as men reviewing EL James novels.
It's that annoying thing where one does not have to be intentionally misogynistic to be in a misogynistic system, and being on the internet often means that the audience, reach, and social impact you plan on having frequently bears no resemblance to the audience, reach, and social impact you do have.
Also there's a bit of an accountability paradox, where making gestures towards a movement, like feminism, seems to include in its social contract an implicit agreement to be open to criticism when one fails from a feminist lens. Which means that something that seems directed to a hugely female audience feels inherently like a more fitting target for feminist criticism than other things that are objectively worse, but have never made any gestures towards feminism at all.
