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?
Unfortunately it’s owned by Amazon now so it inflates the ratings of their shows. But other than that it’s still quite good like you said for getting an overview
