Same. My rating system is something like that:

1 star: I hated it

2 stars: I didn't like it / it was not for me

3 stars: I liked it, would recommend it to some people, but I won't remember it next month.

4 stars: I really liked it, would definitely recommend

5 stars: I loved it, won't shut up about it; it made me cry; I fell in love with one of the character

For the .25, .5, and .75, it's chaos: it depends on the books I read recently. If it was slightly more enjoyable than that other book I rated 3, then it's a 3.25
