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?
I find that rogerebert.com ’s reviews are pretty solid. I use that for a quick tool to decide if I want to watch something - I don’t think i’ve ever been disappointed by a film they rated 3.5-4 stars.
