I agree with this. You form a parasocial bond with the content creator, and then you want to have the same conclusion as they had, to be part of an in-group. I struggle with BookTok and BookTube personally because I straight up have found that I don't like about 50% of what's been recommended. And my experience with personal recommendations is similar, even from people that share similar interests. Two examples: I didn't like "A Darker Shade of Magic" by VE Schwab, I thought the writing was poor, the worldbuilding was vague at best, and the plot was messy. I am also struggling to not DNF "The Lies of Locke Lamora" by Scott Lynch, it's a well written book, the world building seems solid, the various plotlines seem intriguing... I can't get through it, it's a slog for me.
