He may not figure it out. Sadly, a lot of people buy into the narrative that if they get downvoted it might be not because they were rude but because they dared to say a "hot take" and people "can't take it".

And I don't say this because I have stakes in defending Captain Marvel as a movie. I found Captain Marvel AND Batman v Superman to be both rather bad movies. It's not even a controversial take: a lot of people disliked both movies. Some people get very incel-ish about why they dislike Captain Marvel, and that's a big yikes. But that aside, the movie isn't (imho) a very good movie anyway.
