I only liked it a little bit but was recommended by someone for whom it was their favorite book ever.

I only really took away one thing from the book (some deeper level of understanding of what is meant by "quality", in the sense of craftsmanship). I value that understanding and am happy I read the book, but I don't use that wisdom very often in my life.

Maybe you're reading it in a way which expects it to have a plot? I don't know, I think book recs are generally hard and people should only trust book recommendations from people who like books for the same reasons.
