I used to read books just to read and get lost in their magical world. I didn;t care about the way books where written and most of all I didnt pay attention to the characters personality, if I did not like the way a book was written I just dropped it and then started a new one (I could do that from page 1). That continued until recently until last year I started reading reviews and pay a little more attention to the rating of books.
Once I started reading reviews about books that I had already read, I started looking at them differently. Twilight and Vampire Academy weren;t that awesome and ''unique'' anymore and some characters from a loved from a lot of books weren't appealing anymore.
When I started reviewing books I changed completely the way I read, I became more strict with authors and the ways they wrote and developed their characters and plots, sometimes I became mean because simply I was paying for a good book and secondly in my opinion and in my head you have to meet a certain level of professionalism in order to write and publish a book.
I don;t know if thats a good or a bad thing since I notice every little bad detail in the book but sometimes, noticing everything stops me from completing or enjoying some books.
