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?
What I do is go on the wiki page of the movie and check the Reception section. It will have a summary of ratings from various sources, then I can sort of infer if it’s something worth watching by “averaging” the ratings.
