As far as I can tell, the only platform that I found with medium level of reliability is metacritic.
I tried Letterboxd, Serializd, IMDB and Rotten Tomatoes, all of them tend to be very unreliable.
Is there is any other platform that has reliable ratings/reviews?
Rottentomatoes and imdb, but only if you sort by user rating (not critic), and only if you ignore the scores from every movie after like 2015.
