Yeah, not too worried about the people who say they dislike the film for things such as its violence or find it absolutely bleak, as opposed to say somber, melancholy yet hopeful like most reviewers are praising it for. It's personal taste.
Mangold and Hugh have made a critically acclaimed, serious, dramatic and violent R-rated superhero film. As Mike Ryan of Uproxx said, that's basically the holy grail. It'd be nice for the film to tick up a few notches on RT, but it's just small potatoes at this point. (Plus there's a few more rave reviews to come no doubt)
