True, but if the database created here can get enough clicks, it'll start coming up the ranks similar to IMDB and Rotten Tomatoes. Additionally, if people have the incentive of the opportunity to get paid to leave reviews (and the payment wouldn't be influenced by anyone in the movie industry), this could be an even more powerful factor.
Remember when people used to be able to leave reviews not just on movies, but also communicate through message boards back in the day? There was a lot more lively discussion back then, and you'd see a lot more back and forth. They took that feature away in 2017. That could be implemented here instead.
