0 -1 = utter crap and I probably didn't finish it.
1 - 2 = I get why some people liked it but it wasn't for me
2 - 3 = Not bad, but there were some issues I couldn't get over
3 - 4 = I wanted to love it but there were some issues
4 - 5 = I loved it and will recommend it to everyone!
I also gives ratings not in stars but in aspects from the book ... so look out for that!
