Somewhat-Reticent Trolls (fastest), shills (2nd fastest), AI-gens, … or Real_Human™reviews?
While we all know that Rotten Tomatoes is absolutely disreputable, IMDB is pretty good, I haven’t seen them game the review system like Rotten Tomatoes and I usually agree with most of the reviews. I posted a few up there and they stuck but ⅓ of my Rotten Tomatoes reviews are gone to the ether because they don’t match the wills of the owners.
