I might be a weird one, but I don't usually look at reviews for whether to read or not. I mean, it might affect WHEN I read, but I'm usually set on reading the book when I get it. I also like to see where I fall with the book compared to other reviews so I usually try not to read or look at rating until partway into or finished with the book.

Also I rank a bit different- at least from the suggested list I saw someone share.

1- terrible

2- not good, but readable

3- "it's a book"/mid-level, nothing outstanding or overly memorable

4- (better, if in a series if 3 books) good/very good, something interesting about it makes it well worth the time

5- one of my favorites, would revisits multiple times/ unique in some manner

That being said, I've only ever given 2 books a 1 star (I had to read for school), with most being a 3 or 4 star rating.
