Book ratings are hard... Do I give a 5 star because I love something or is it more than that? it's got to be more...right?

I think I've finally decided:

5⭐ : couldn't put it down, lives in my brain loved the characters, the plot, completely absorbed.- will fight people to read more
4⭐: really enjoyed, struggled to it down, enjoyed the overall story and will read more by the author always
3⭐: enjoyed and finished the book happily. might read more but not necessarily leaping lines to get there.
2⭐: it was okay. I didn't necessarily hate it but didn't love it either. probably unlikely to read more.
1⭐: very likely hate read as I can't dnf a book.
