The recommendations from Goodreads are quite bad. This is for two reasons, I think. The categories that are used can sometimes be quite broad and so the programmatic recommendation pages can be quite useless. Far too many books in a broad category that don't give recommendations that are really related to a specific book that you read.
Secondly, people are not really the best at reviewing content. Taste is particular, of course, but many people can't differentiate between 'I didn't like this' and 'this is poorly written'. I am currently reading 'The Cold, Cold Ground' [^1] by Adrian McKinty and I doubt I will finish it because it is utterly bleak. It is a very well done book but it isn't for me. I would say that in a review but many people don't. So you get enthusiastic reviews for books that are utter shit as well as similar reviews for good books and it is difficult to tell them apart.
[^1]: I can't read the title without thinking of the quote from the Tasmanian Devil. "What for you bury me in the cold, cold, ground". https://youtu.be/CzDtYJLfA9Q
