5 is I absolutely loved it and want to reread (if I find time).

4 is great book, really enjoyed it, and would probably reread but only if I was really in the mood/it's part of a series/I have nothing else I'm clamoring to start.

3 is I liked it but it may not have stood out in any way as really good.

2. I really did not like it and it was a struggle to finish.

1 is I DNF. Since starting a Goodreads (4-5 years ago) I have never DNFed, but I came close a few times.

Goodreads ratings are not holy to me and my baseline rating is like a 3.5 (jesus christ i wish half stars were possible). But what i mean is I give nearly everything a 3 or a 4 (and honestly probably more 4s than 3s). I give a healthy amount of 5s. All of my ratings are (obviously) subjective, and a book that maybe is a 4 can become a 5 merely by me being pleasantly surprised by how much I liked it. Similarly a 4 could become a 3 if I had higher hopes.

Because of the good people here on /r/books and /r/fantasy I generally find that by and large I really do enjoy the things that I start. People give good recommendations. And there are a lot of excellent books to read. Too many.
