I agree. Letterboxd makes this easy to accomplish with movies, and there's enough people covering videogames out there that you can usually find someone to dial-in on your taste (or find a Steam curator that lists a lot of stuff you love). TV is a bit harder, but you may be able to find a critic with a consistent voice that matches your own through Rotten Tomatoes (not the aggregate score alone) or maybe a podcast about TV where you learn their preference dial vs. your own.
But books? The level of investment to make these determinations is larger, and there's less people doing it. Or maybe I just haven't found the answer yet.
I also don't think it helps that people either like a book or immediately say "bad writing" or "too YA", which then make others that disagree look like simpletons just for disagreeing. Creates a hard place for dialogue.
the answer is to use goodreads, follow people who you really like/agree with the reviews of, and then only read their reviews of any book you might want to read
I just really struggled with Goodreads, but that was years ago, maybe I'll give it another shot. Or perhaps try this Storygraph thing another commenter mentioned.
There is also much nicer version of goodreads https://literal.club it started as answer to amazon acquiring goodreads. It has fewer users than good reads but i would say generaly more demanding readers (judging from what kind of books get reviews).
