I had to laugh at this - "Every review carries the same weight whether it runs in a major newspaper or a Substack with a dozen subscribers." Yeah, and that's a good thing. Why should subscriber base give your review more weight? I can read that individual's review if I want to know what they think, I don't need to get a higher weight for the total review from everyone.
Then this was just as laughable - "Misogynist trolls had hijacked the platform, coordinating to tank women-led movies like Captain Marvel before they opened." No, it was an objectively BAD movie with an actress that acts like a stiff unenthused robot delivering her lines.
In conclusion, this author thinks RT needs be fixed because it's not reflecting his bias that the movie industry needs to be more "inclusive" and no movie that includes that "inclusivity" ought to ever receive a poor rating because obviously all of those ratings are racist, misogynist, -ist this, -ist that etc.
Here's my prescription: Just watch the movies and make your own mind up. If you have to go to a site like RT, ignore the critic reviews completely because almost all live in a bubble and can't relate with common movie goers.
