I left r/movies many years ago. I found that any new release movie under discussion was heavily policed by promoters and marketers with masses of bot accounts to downvote critical comments. So, one example was Alien Covenant, which was a stinker of a film.
I saw it on release, and the review posted at r/movies gave it a big thumbs up. But I'd seen it and I knew it was an awful film. So I said so and got downvoted like thirty times. Everyone who had seen the film and told the truth were bombed with masses of downvotes. Everyone who promoted the film got masses of fake up votes.
This kept happening for so many new releases I just gave up on the sub. I can't be alone there.
