I picked this almost at random, I don't recall anything controversial about Ant-Man or Frozen and the scores more or less line up within reason. There is always going to be some movies critics like a little more and vice versa, the spread here is fairly small.
Captain Marvel is at 81/36, which shows something more along the lines of The Last Jedi which today stands at 91% critics, 44% public.
I would wager the public rating for TLJ is far more accurate than the critic rating and suspect the same for CM. Movies that have an agenda to be pushed get "help from the critics" which any half way decent movie doesn't require, see Frozen, Ant-man I and II. Several reviewers I trust (were talking years and years of reviews) all state the same thing.
The movie is flat, the actress comes across as boring, she has zero character arc, CM can do everything first shot, men are beat on in the movie while women can do no wrong.
Hell the trailers are boring as hell, Fury and the cat look more interesting.
We saw the same thing in The Last Jedi, Disney telegraphed from miles away they were going to do the same thing here and they did.
Want to see an interesting female character? See Prospect instead. Close as I'm going to get to a spoiler.
