For me the first thing that comes to mind is Tales from Earthsea. I don’t think it’s excellent or anything and has plenty of problems but people act like it killed their dog. While it has its problems that have been covered extensively, I think it has a beautiful atmosphere and art.
IMO it would have been better received if it wasn’t advertised as an Earthsea adaptation and was just its own thing.
I just watch content creators or reviewers whose taste matches with mine and check their recommendations first. Otherwise check 2 or 3 positive and negative reviews in imdb, rt, Google. You can roughly tell who are shills, trolls or giving valid criticisms.
