You could be my absolute favorite blogger in the entire blogging universe who writes better reviews than anyone ever, and I still won't read it. Basically, this is your classic "It's not you, it's me" situation.
Well, it's a pretty simple answer, actually: I'm not going to read your review because I want to go in with an untainted mindset. If I'm reading a sequel that means I really liked the first book. This means high hopes and expectations that I don't want to become too inflated or deflated by reading a review. I want my opinions about the book to be my own, instead of influenced by someone else's.
I want it to be the ideal, unspoiled reading experience.
*But there is an exception...
...which is I didn't like the first book THAT much.
It was one of those meh books. Worthy of 3 stars, maybe a little less, but the series shows potential. Do I want to spend the time reading the next one? Well, I guess I'll have to see what one of my favorite blogs thought to find out.
**Also (and yes, I know I'm really not using this asterisk thing right, but bear with me anyway), I will read reviews for the sequels after I finish them because I'll be interested to see if we felt the same way about a book. And I like talking to people about books (in case you haven't noticed).
